For solving problems A5 Unified State Exam in informatics, you need to be able to execute algorithms written in natural language. It is also necessary to have.
For example, consider solving problem A5 in computer science from training work 2 of 15.02.2013.
The teacher invited the children to practice actions with hexadecimal numbers and play such a game. He offers the children three hexadecimal digits, in ascending order. Students must first find the difference between the first and second digits, then the difference between the second and third digits. Both differences must be recorded as decimal numbers. Then these numbers are written one after another in non-increasing order (the right number is less than or equal to the left).
Example. Initial figures: A, A, 3. Differences: A - A \u003d 0; A - 3 \u003d 10 10 - 3 10 \u003d 7 10. Result: 70.
1) 131 2) 133 3) 212 4) D1
Decision:
The 4th option does not suit us for the reason that the number D1 is not decimal. That is, it contradicts the condition of the problem in the part "Both differences must be written as decimal numbers."
Consider the third number - 212. This number can be represented as 2 and 12, or as 21 and 2. According to the condition, the final numbers are written in non-increasing order - so you need to consider only option 21 and 2. The condition says that the original numbers - hexadecimal. That is, in the decimal number system, these are numbers from 0 to 15. It is clear that it is impossible to choose such numbers (from 0 to 15), the difference of which will be 21. This option is also not suitable.
The second option, by analogy with the first, is represented as 13 and 3. The number 13 can be obtained by subtracting 2 from 15, subtracting 1 from 14, or subtracting 0. But after that we must subtract more from the subtracted (2, 1 or 0) some number and eventually get 3. But this is impossible. Wrong option.
The first option is presented as 13 and 1. But here everything is correct. 13 can be represented as 15 - 2, and 1 \u003d 2 - 1 - the original numbers could be like this - F, 2, 1. This is correct option.
Consider decision second option:
The teacher invited the children to practice actions with hexadecimal numbers and play such a game. He offers the children three hexadecimal digits, in ascending order. Students must first find the difference between the first and second digits, then the difference between the second and third digits. Both differences must be recorded as decimal numbers. Both differences must be recorded as decimal numbers. Then these numbers are written one after another in non-decreasing order (the left number is less than or equal to the first).
Example. Initial figures: B, 3, 3. Differences: B - 3 \u003d 8 10; 3 - 3 \u003d 0. Result: 08
Indicate which of the following character sequences can be produced.
1) 122 2) 212 3) 313 4) 3A
Decision:
Option 4 does not work because 3A is not decimal.
Option 3 is represented as 3 and 13. 13 can be represented as 15 - 2 (or 14 - 1), but then we will need to subtract an unknown digit from the number 2 (or 1) and get the result 3. This is impossible.
We represent the second option as 2 and 12. Then 12 can be represented as 15 - 3, and 2 \u003d 3 - 1. Everything turns out - this is the correct option.
The first option is wrong. Let's represent the number 122 as 1 and 22. It is clear that by subtracting two numbers, each of which is no more than 15, you cannot get 22.
Consider solving problem A5 of the Unified State Exam Demo in Informatics 2013
The machine receives two two-digit hexadecimal numbers as input. In these numbers, all digits do not exceed 6 (if the number contains a digit greater than 6, the machine refuses to work). Based on these numbers, a new hexadecimal number is built according to the following rules.
1. Two hexadecimal numbers are calculated - the sum of the most significant digits of the received numbers and the sum of the least significant digits of these numbers.
2. The resulting two hexadecimal numbers are written one after the other in ascending order (without separators).
Example. Initial numbers: 66, 43. Bitwise sums: A, 9. Result: 9A.
Determine which of the proposed numbers can be the result of the machine.
1) 9F 2) 911 3) 42 4) 7A
Decision:
Let's consider the first option. We represent the number 9F as 9 and F. Since the initial numbers do not exceed 6, it is impossible to find such numbers, the sum of which will be 15 (F 16 \u003d 15 10). This is not the correct option.
Since the original numbers do not exceed 6, their maximum sum will be 6 16 + 6 16 \u003d C 16 \u003d 12 10, which is less than 11 16 \u003d 17 10. Those. the case is similar to the previous one and this is also a wrong option. In addition, the sum of two hexadecimal numbers not exceeding 6 cannot be two-digit.
The third option is not suitable, since the numbers are written in descending order, which contradicts the condition.
We get that the correct option is 4. Let's check it out. We represent the number 7A as 7 and A. Now it is not difficult to represent 7 16 as 3 16 + 4 16, and A 16 as, for example, 5 16 and 5 16. Then everything is correct - the two original numbers could be 53 16 and 54 16. If now the first point of the condition is fulfilled and the higher digits are added, then we get 5 16 + 5 16 \u003d A 16, and the sum of the lower digits is 3 16 + 4 16 \u003d 7 16, and then after the second point of the condition is fulfilled, we get the number 7A 16. The correct option is the fourth.

If you can't find all the errors, refer to the examples below. Material for expanding speech experience is systematized by topic. You should be aware of the typical cases of violation of syntactic norms.
Erroneous constructions
1. Management
one). Verbs with different controls as homogeneous members of a sentence:
Words with different controls can be used as homogeneous members if each of them has its own dependent words used in the required case. For example:
She was waiting for him and called him all evening.
She was waiting (for whom?) him(V.p.) and called (who?) him(D.p.) all evening.
Pronouns often help to build such sentences correctly:
Children rarely listen to and follow the advice of adults.
Children rarely listen (to what?) To advice (D. p. With the pretext to) adults and follow (what?) them(D.p.).
People were exhausted, but they believed in victory and hoped for it.
People were exhausted, but believed (in what?) In victory (V. p. With the pretext in) and hoped (for what?) on her(D.p. with the preposition on).
2). Different controls for verbs and nouns:
be interested in art (Ect.) - interest in art (D.p.)
love literature (V.p.) - love of literature (D.p.)
hate the mess (V.p.) - hatred of disorder (D.p.)
respect colleagues (V.p.) - respect for colleagues (D.p.)
trust a friend (D.p.) - trust in friends (D.p.)
sympathize with the weak (D.p.) - sympathy for the weak (D.p.with a preposition)
3). Different controls for words with similar meaning:
worry about anything (P.p.) - worry about something (V.p.)
pay something (V.p.) - s pay for something (V.p. with the preposition per)
pay the fare (V.p. with the preposition per) - pay for travel (V.p.)
pay attention to something (D.p.) - pay attention to something (V.p. with the preposition on)
tell anyone (D.p.) - inform anyone (V.p.)
to reproach (P. p. With the preposition in) - condemn for something (V.p. with the preposition per)
feedback about something (P. p. With the preposition about) - review of anything (V.p. with the preposition on)
belief in anything (V.p. with the preposition in (in)) - confidence in anything (V.p. with the preposition c)
intrinsic (D.p.) - characteristic of something (R.p. with the preposition for)
4) Different controls for verbs with and without negation:
notice the reaction (V.p.) - not notice the reaction (R.p.)
He noticed (what?) the reaction of the audience to his words. - With excitement, he did not notice (what?) the reaction of the audience to his words.
5) The use of titles of works of literature and art.
In War and Peace, actor V. Tikhonov played the role of Prince Andrei.
In the film "War and Peace" actor V. Tikhonov played the role of Prince Andrey.
After words - generic designations, for example, fairy tale, novel, novella, story, picture, motion pictureand others like that, calling the genre of a work of literature or art, a proper name is put in the nominative case. If there are no such words in the sentence, then the names of works of literature and art are used in those cases that are necessary for the context of the sentence.
In the fairy tale "Turnip" or: In the "Repka"
In the movie "War and Peace" or: In "War and Peace"
In the ballet "The Nutcracker"or: In the Nutcracker
Remember:
Many verbs require a specific case after themselves.
The verbs require the genitive case:
Reach, seek, desire, crave, want, expect, do, fear, beware, fear, avoid, lose, be afraid, ashamed, shun, stand, seek, ask, demand and others (who? what?)
Negative verbs: do not see, do not notice, do not hear and others (who? what?)
The dative case is required by verbs:
Give, believe, trust, threaten, indulge, learn, rejoice, smile, speak, respond, threaten, threaten, object, bow, nod, wave, honk, call, write, speak, tell, announce, answer, explain, report, like, seem, interfere, harm, take revenge, change, harm, take revenge, annoy, dislike, give, buy, bring, send, show, help, promise, dream, etc. (to whom; to what?)
All transitive verbs require the accusative case:

Say, explain, announce, inspire, tell, declare, answer, promise, recommend something to someone
Promise, guarantee anything to anyone
Teach someone something
Count, imagine, recognize, imagine, name, depict, curse, declare someone to be someone
Standard options
To want, to desire, to crave, to ask, to deserve a reward - rewards (V.p. and R.p.), but: earn a reward (V.p.)

Attention:
Miss (for what? To whom?) For work, for home, for mother, for husband. But with the pronouns: miss (who?) For us, for you. This use of pronouns in the prepositional case has long been considered the only correct one.
For example, in D. E. Rosenthal's reference book "Management in the Russian language" it is indicated that it is correct with nouns and pronouns of the third person: miss someone, eg: miss your son, miss him. But with personal pronouns of the 1st and 2nd person pl. the numbers are correct: miss someone, eg: missed us, miss you.
But recently both options have been recognized as acceptable. It is believed that since bunch(and sad, longingetc.) for you - the old norm; for you - new. Today these options compete, which is reflected in reference books. So, "Russian grammar" (M., 1980) forms miss you and miss you considers as variable.
2. Constructions with prepositions
1 ) prepositional control:
thanks, according to, in spite of, in spite of, like + D.p. noun, for example: contrary to instructions, rules, opinion of relatives, according to order...
by (meaning "after something") + P. p. noun, for example: on arrival, on return, at the end of the experiment...
in measure, in force, during, in continuation, in conclusion, for reason, after completion, like, by + R.p. noun,
eg: in the course of the conversation, in a week..
.
2) use of prepositions in non-sentence constructions:
The article served as an impetus for thoughts.
Wrong: to thoughts
Wrong: to the manufacturer
3) prepositions for homogeneous members of the sentence:
I need to go to the station, to the post office and to the store.
Classes are held at the stadium, in the park and in the hall.
If different prepositions with different nouns are required, they should be used. Skipping prepositions in such cases is unacceptable.
4) prepositions to, na - s, from:
In Kamergersky lane, shop in Kamergersky
on the street, shop on Tverskaya
From Rostov, from the theater, from the store, from the park, from exile, from the circus, from the club, from the conservatory, from the restaurant, from the school, from the class, from the airport, from the port, from the institute, from the university, from the library, from the hospital
from the south, from the square, from the boulevard, from the post office, from the market, from a lecture, from a performance, from a concert, from a station, from a train station
3. Using the full form of adjectives instead of short
1) short forms of adjectives act as predicates:
Sister sick already a week.
Wrong: Sister has been sick for a week.
This photo road us.
Wrong: This photo is dear to us.
2) full and short forms are not used as homogeneous members of a sentence:
Sister was beautiful and sad.
Inaccurate: The sister was beautiful and sad.
4. Sentences, the subordinate part of which begins with the union word who
Relative pronoun who in the function of a union word, it is used only with verbs in the singular, for example:
Whoever writes the USE for 85 points or higher has an excellent chance to enter the most prestigious universities.
Those who are not late will participate in the competition.
The subject and predicate in the main part must be either singular or plural. The predicate cannot be used in the singular, if the subject is in the plural, and vice versa. For example:
Those, who will write the exam for 85 points or higher, will be able to enter to the most prestigious universities.
Everything, who will write the exam for 85 points or higher, will be able to enter to the most prestigious universities.
5. Violations in participial sentences
1) harmonization of the participle with the defined word:
Herbs, (what?) used for the manufacture of drugsare collected in China.
He asked the audience a number of questions (what?) exciting everyone.
Katerina's protest, (what?) defending their rights, is shown in this production in a new way.
2) mixing of passive and real participles:
The task, carried out by us, is not difficult.
Invalid: An assignment performed by us.
3) combination of constructions a) with participle and b) with which the:
Rain, poured in the morning and prevented our walk, ended in the afternoon.
The rain that had been pouring down in the morning and interfering with our walk ended in the afternoon.
Mistaken: The rain that had been pouring in the morning and which interfered with our walk ended after lunch.
6. Sentences with a union word which the
These are complex sentences with a relative clause.
1) It is wrong to make a gap between the defined word and the relative clause with the word which the:
Wrong: I want to pass the exam in Russian, mathematics, and history, which I have not done seriously before.
Correctly: I want to pass the exam in mathematics, history and the Russian language, which I have not seriously studied before.
Incorrect: Look at my mom's birthday present that my sister made herself.
Correctly: See the gift my sister made herself for my mom's birthday.
2) erroneous word control which:
Wrong: Yesterday snow fell, and we were all delighted.

7. Erroneous transmission of indirect speech
Wrong: Petka said that I was not ready for the exam yet. (Petka said: - I'm not ready for the exam yet)
Pronouns of the 1st and 2nd person are not used in indirect speech.
Correctly: Petka said that he is not yet ready for the exam.
Wrong: Petka said that he was waiting for his mother, who should come. (Petka said: - I'm waiting for my mother, who should come)
Correctly: Petka said that he was waiting for his mother, who was supposed to come.
8. Proposals with double unions
1) wrong arrangement of unions in a sentence:
Both ... and ...
Not only but…
If not ... then ...
Not so much ... as ...
Not that ... but ...
Wrong: Exams not only passed the ninth, but also the eleventh grades. (Violation of logic, the union is used incorrectly)
Correctly:Not only the ninth, but also the eleventh grades passed the exams.
2) mistaken doubling of the union than: rather than:
Wrong: He is more talented than his brother. (Union than plain)
Correctly:He's more talented than his brother.
3) violation of the structure of the union not so ... than instead not like:
Wrong: My bag is not as pretty as my friend's. (Allowed distortion of the type of union because)
Correctly: My bag is not as pretty as my friend's. Or: My bag is less beautiful than a friend's.
Wrong: He did not perform as well as his friends. (Allowed distortion of the type of union because)
Correctly: He did not perform as well as his friends. Or: He performed less well than his friends.

1. General information
Difficulty: basic.
Estimated solution time (for those who will be doing part 2): 2 minutes
Subject: Algorithms and programming
Subtopic: Algorithm Analysis in Natural Language
What is checked: Ability to formally execute an algorithm written in natural language. Ability to analyze the set of possible results of an algorithm, a set of input values \u200b\u200bleading to a given result.
Comment... A special case of the algorithm execution is checking the truth of the condition.
General view of the task:
A certain algorithm is described. An example of how the algorithm works for a certain set of input data is given: input data, result, possibly intermediate values.
4 objects are given (numbers, words, etc.).
Examples of questions:
1) Determine which of the given objects can (cannot) be the result of the algorithm.
2) Determine which of the given objects can (cannot) lead to a given result.
Comment. If we impose additional conditions (smallest, largest, etc.), then instead of the problem of the format of part A "indicate who belongs to a given set" we get the problem of the format of part B - to indicate the (only!) Element of the set that satisfies the additional condition.
2. Example from the demo
2.1. The task.
Task 2012-A5-1.
1. Three numbers are calculated - the sum of the most significant digits of the given three-digit numbers, the sum of the middle digits of these numbers, the sum of the least significant digits.
2. The resulting three numbers are written one after another in descending order (without separators).
Example. Initial three-digit numbers: 835, 196. Bitwise sums: 9, 12, 11. Result: 12119
Determine which of the following numbers can be the result of the machine.
1) 151303 2) 161410 3) 191615 4) 121613
2.2. Solution sketch.
The sum of two single-digit numbers can be either a single-digit number (from 0 to 9) or a two-digit number - from 10 to 9 + 9 \u003d 18.
Since all four given numbers are six-digit, all intermediate sums are two-digit. For a 6-digit number to be the result of the algorithm, it is necessary and sufficient that the two-digit numbers composing it satisfy the following conditions:
a) they are all in the range from 10 to 18;
b) each next (from left to right) number is less than or equal to the previous one.
Consider the numbers indicated in the condition.
1) Doesn't fit. The third pair starts from zero (condition a) is not met)
2) OK. Possible initial three-digit numbers: 875 and 875, 999 and 751, etc.
3) Doesn't fit. The first pair is equal to 19 (condition a) is not satisfied)
4) Doesn't fit. The second pair is greater than the first (condition b) is not met)
A. Strong learners .
1. Most likely, they will solve this problem anyway.
2. If not, pay attention to the key points:
Splitting a six-digit number into pairs;
Which pairs are impossible (19 and more, as well as those that start from zero), it is better if the students themselves formulate these conditions.
3. Come up with your own approaches and try them. J
B. Not so strong students .
1. The first (perhaps the main) difficulty is the very condition of the problem. Have the students run the described algorithm for several inputs. Make sure everything is done correctly.
2. Ask the students for a given six-digit number to come up with a pair of three-digit numbers leading to this result (the problem should be solvable). Suggest that you come up with a few more pairs that lead to the same result.
3. Invite the students to come up with a number that can NOT be the result of the algorithm. Even if they don’t come up with anything, it will help to understand your explanations.
4. Point out to students that six-digit numbers are uniquely split into three two-digit numbers.
5. Find out with the students which pairs are impossible (19 and more, as well as those that start from zero), it is better if the students themselves formulate these conditions.
6. Consider in turn the four given numbers. If the student has difficulty with a number, ask the student to come up with a pair of three-digit numbers leading to the given answer.
7. Come up with your own approaches and try them. J
1. Read the problem statement. Try to come up with conditions necessary and sufficient for the object to be the result of the algorithm (for the problem 2012-A05-1, these are conditions a) and b)). At worst, formulate the necessary conditions; it is not necessary to prove the sufficiency in general form. If you could not come up with the necessary conditions, do not waste a lot of time on this (no more than 1 minute). Start looking at candidate objects.
2. Consider each candidate object in turn. For each object, try to think of the input that this object outputs. If it works, the problem is almost solved (see item 3). If it doesn't work, try to prove it's impossible. If proved, we delete the object from the list of candidates and move on. If not, then we will return to this object.
3. What to do if you find an object that satisfies the condition of the problem. Better to look at the rest of the objects and make sure that they do not fit the condition. If this does not work out, you can find a mistake in yourself and fix it.
4. What to do if it was not possible to delete all objects, except one, and for this one to prove that the condition is satisfied for it. If of the remaining there is exactly one object for which you can prove (or are simply sure) that the condition is met, choose it. If there are several or none of such objects, you have to guess. Good luck!
