Answer:
Artist The draftsman moves on the coordinate plane, leaving a trace in the form of a line. The draftsman can execute the command Move to (a, b)(where a, b- integers), moving the Draftsman from the point with coordinates (x, y) to a point with coordinates (x + a, y + b)... If the numbers a, b positive, the value of the corresponding coordinate increases; if negative, decreases.
For example, if the Draftsman is located at a point with coordinates (4, 2) , then the command Move to(2, −3)will move the Draftsman to a point(6, −1).
Repeat k times
Team1 Team2 Team3
means that the sequence of commands Team1 Team2 Team3 will repeat k once.
The draftsman was given the following algorithm for execution:
Repeat 3 pa
Move by (1, 1) Move by (2, 2) Move by (1, −3) End
What command should the Draftsman execute in order to return to the starting point from which he began to move?
1) Move to (12, 0)
2) Move to (0, 12)
3) Move by (0, -12)
4) Move by (-12, 0)

Answer:
Some algorithm from one string of symbols gets a new string as follows. First, the length of the original character string is calculated; if it is odd, then the first character of the chain is removed, and if it is even, then the character T is added to the middle of the chain.In the resulting chain of characters, each letter is replaced by the letter following it in the Russian alphabet (A - to B, B - to C, etc.). and I - on A). The resulting chain is the result of the algorithm.
For example, if the original chain was LEG OPUDB, and if the original was a chain DREAM, then the result of the algorithm will be the chain ON.
Given a character string QTY... What chain of symbols will be obtained if the described algorithm is applied twice to this chain (i.e., apply the algorithm to this chain, and then apply the algorithm again to the result)? Russian alphabet: ABVGDEEZHZYKLMNOPRSTUFHTSCHSHSCHYEYUYA.

Column A contains the student's last name and first name; in column B - the student's school number; in columns C, D - points obtained, respectively, in geography and computer science. For each subject it was possible to score from 0 to 100 points. A total of 272 students were included in the spreadsheet. The order of entries in the table is arbitrary.
Complete the task.
Open the file with this spreadsheet (the exam organizers will tell you the location of the file). Based on the data in this table, answer two questions.
1. How many students in school No. 2 scored more points in computer science than in geography? Write the answer to this question in cell F3 of the table.
2. What percentage of the total number of participants were students who received more than 50 points in geography? Write your answer to one decimal place in cell F5 of the table. task19.xls
The solutions for the expanded answer tasks are not automatically checked.
The next page will ask you to test them yourself.
Choose ONE of the tasks below: 20.1 or 20.2.
Performer The robot is able to navigate a maze drawn on a plane divided into cells. There can be a wall between adjacent (on the sides) cells, through which the Robot cannot pass. The Robot has nine teams. Four commands are command commands:
up down left right
When any of these commands are executed, the Robot moves one cell, respectively: up and down ↓, left ←, right →. If the Robot receives the command to move through the wall, it will collapse. The Robot also has a command paint over, at which the cell in which the Robot is at the moment is painted over.
Four more commands are commands for checking conditions. These commands check if the path is clear for the Robot in each of the four possible directions:
top free bottom free left free right free
These commands can be used in conjunction with the condition "if" that looks like this:
if condition then
sequence of commands
Here condition- one of the commands for checking the condition. Sequence of commands Is one or more of any command-orders. For example, to move one cell to the right, if there is no wall on the right, and painting the cell, you can use the following algorithm:
if the right is free then
paint over
In one condition, you can use several commands for checking conditions using logical connectives and, or, not, For example:
if (right is free) and (not below free) then
To repeat a sequence of commands, you can use the loop "bye" which looks like this:
nc bye condition
sequence of commands
For example, to move to the right while possible, you can use the following algorithm:
nts so far on the right is free
Complete the task.
On an infinite field, there are two identical horizontal parallel walls, located one below the other and spaced from each other by more than 1 cell. The left edges of the walls are flush. The lengths of the walls are unknown. The Robot is in a cage located directly under the bottom wall. The figure shows one of the possible ways to position the walls and the Robot (the Robot is marked with the letter "P").
Write an algorithm for the Robot that fills in all the cells below the horizontal walls. The robot must paint only cells that meet this condition. For example, for the above picture, the Robot should paint over the following cells (see picture).
The final location of the Robot can be arbitrary. The algorithm must solve the problem for an arbitrary size of the field and any acceptable location of walls within a rectangular field. When executing the algorithm, the Robot should not collapse. The algorithm can be executed in the environment of a formal executor or written in a text editor. Save the algorithm in a text file.
20.2 Write a program that, in a sequence of natural numbers, determines the number of multiples of 3. The program receives as input the number of numbers in the sequence, and then the numbers themselves. The sequence always contains a multiple of 3. The number of numbers does not exceed 100. The entered numbers do not exceed 300. The program should output one number - the number of multiples of 3.
In general, what are we talking about? ..
The last parameter allows you to select one of the search results - this is the first level of the hierarchy (Match Object). Groups, only if highlighted, are nested in each of these results - the second level of the hierarchy (Matches Collection). You all have full matches, because they can never be different. But even if you select a group using parentheses (capture occurs), you still cannot refer to it. In the template itself, you can refer to the group through the syntax \1
(exactly like that: via backslash), but that's not what you want. It has nothing to do with your task.
Search results can be as many as words in a sentence. But you can break each word, for example, into letters, and then in each search word there will be several selected letter-groups. Something like this. But why do you need this? The author of one function has solved how many problems!
Try this pattern (regex101 doesn't find anything, but VBScript does):
^.*(?=/[^/]*)$
Explanation. Within a line from the beginning ^ to end $ find a sequence of any characters .* before a single slash character set / and sequences, conversely, of any characters other than the slash [^ /] *. Anything in parentheses is a group (look ahead), read the manual.
Author function RegExpExtract () does not give the ability to refer to groups. What is in parentheses in the template is indeed a group, but the RegExp.Replace () method, which is not used in the author's function, provides the ability to work with such a group.
Implement your RegExpReplace (Text, Pattern, Replace) function, in the body of which insert the RegExp.Replace (Text, Replace) method.
The function will be no longer than the first. It's simple.
Text is the original text,
Replace - a string (using patterns of links like $ 1), which should be replaced in the original string Text with the search result by pattern Pattern.
In order to make it convenient to make replacements, it is advisable to find the whole line and highlight in it required groups.
In our case, like this:
(.*)/.*
| Match 1 | ||
|---|---|---|
| Full match | 0-9 | `1/2/3 / pin ` |
| Group 1. | n / a | `1/2/3 ` |
RegExpReplace ("1/2/3 / output"; "(. *) /.*"; "No. $ 1")
The returned result will be like this:
№1/2/3
But if you want to replace a substring or, even better, delete it completely in the original text, then like this:
RegExpReplace ("1/2/3 / output"; "(. *) /"; "")
The returned result will be like this (the result of searching for a pattern will be "1/2/3 /"):
vyv
You can refer to a group when manipulating strings (not in a template) using the syntax $1
(exactly like this: through the dollar sign).
If I understand you correctly.
If you do not need substring manipulation by substitution, then follow the rule:
write templates (reg. expression) so rigidly that only one thing is found (retrieved), or make several calls according to a more general template, but specify which result in order (Item parameter) should be returned. Combine the results of independent function calls, process, etc. By and large, you can operate on the search results as your groups (only without links like $).
