The problem asks to create an algorithm for swapping the values of two variables 'a' and 'b' using an auxiliary variable 'm'. The available blocks are: a=b, End, m=a, Start, Input a, b, Output a, b, b=m. Which blocks should be used and in what order to achieve the swap?

The Goal:

The task is to swap the values of two variables, a and b, using a temporary variable m. This is a fundamental programming concept used to exchange data between two storage locations.

Algorithm Steps:

Here's the logical sequence of operations to swap a and b:

1. Start: Initialize the process.
2. Input a, b: Get the initial values for variables a and b from the user or another source.
3. m = a: Store the current value of a in the temporary variable m. This preserves the original value of a before it's overwritten.
4. a = b: Assign the value of b to a. Now, a holds the original value of b.
5. b = m: Assign the value stored in the temporary variable m (which is the original value of a) to b. Now, b holds the original value of a.
6. Output a, b: Display the new values of a and b, which have now been successfully swapped.
7. End: Terminate the process.

The Solution:

Based on the available blocks, the correct sequence to achieve the swap is:

• 4. Начало (Start)
• 5. Ввод а, b (Input a, b)
• 3. m = a
• 1. a = b
• 7. b = m
• 6. Вывод а, b (Output a, b)
• 2. Конец (End)

This sequence correctly implements the temporary variable swapping algorithm.
