Let's analyze the condition in the program: if (s > -3) and (t > 2). The program outputs "YES" if this condition is true, and "NO" otherwise.

We need to find the pairs (s, t) for which the condition (s > -3) and (t > 2) is FALSE. This means either s <= -3 OR t <= 2 (or both).

Let's check each pair:

  • 1) (5, 8): Here, s = 5 and t = 8.
    • Is s > -3? Yes, 5 > -3.
    • Is t > 2? Yes, 8 > 2.
    • Since both conditions are true, (s > -3) AND (t > 2) is TRUE. The program will output "YES".
  • 2) (-5, 8): Here, s = -5 and t = 8.
    • Is s > -3? No, -5 is NOT greater than -3.
    • Is t > 2? Yes, 8 > 2.
    • Since the first condition (s > -3) is false, the entire AND condition is FALSE. The program will output "NO".
  • 3) (3, -11): Here, s = 3 and t = -11.
    • Is s > -3? Yes, 3 > -3.
    • Is t > 2? No, -11 is NOT greater than 2.
    • Since the second condition (t > 2) is false, the entire AND condition is FALSE. The program will output "NO".
  • 4) (-4, 0): Here, s = -4 and t = 0.
    • Is s > -3? No, -4 is NOT greater than -3.
    • Is t > 2? No, 0 is NOT greater than 2.
    • Since both conditions are false, the entire AND condition is FALSE. The program will output "NO".
  • 5) (-3, 2): Here, s = -3 and t = 2.
    • Is s > -3? No, -3 is NOT greater than -3.
    • Is t > 2? No, 2 is NOT greater than 2.
    • Since both conditions are false, the entire AND condition is FALSE. The program will output "NO".

The pairs for which the program will output "NO" are: 2, 3, 4, 5.

We need to write the numbers of the selected pairs in ascending order.

Ответ: 2, 3, 4, 5
