Вопрос:

The image shows a program written in four programming languages: Algorithmic language, Python, C++, and Pascal. All four programs implement the same logic: initialize a variable 's' to 0, then iterate from i = 0 to 12. Inside the loop, if 'i' is greater than 9 and less than 20, add 'i' to 's'. Finally, print the value of 's'. What is the final output of the program?

Analysis of the program logic:

The program initializes a variable s to 0.

It then iterates with a variable i from 0 up to (but not including) 13. This means i will take values 0, 1, 2, ..., 12.

Inside the loop, there is a condition: if 9 < i < 20.

For the values of i from 0 to 12, the only values that satisfy the condition 9 < i < 20 are 10, 11, and 12.

So, the variable s will be updated as follows:

  • When i = 10: s = s + 10 (s becomes 0 + 10 = 10)
  • When i = 11: s = s + 11 (s becomes 10 + 11 = 21)
  • When i = 12: s = s + 12 (s becomes 21 + 12 = 33)

The program then prints the final value of s.
