Given the provided code snippets in different programming languages, identify the core logic and the output for the input pair (4, 1).

The provided code snippets demonstrate a simple program that compares two integer variables, s and k. The core logic is to check if s is greater than or equal to twice the value of k (s >= 2 * k). If this condition is true, the program outputs "ДА" (YES). Otherwise, it outputs "НЕТ" (NO).

Let's trace the execution with the input pair (4, 1):

1. The input values are assigned: s = 4 and k = 1.
2. The condition s >= 2 * k is evaluated: 4 >= 2 * 1, which simplifies to 4 >= 2.
3. This condition is true.
4. Therefore, the program will output "ДА".

The outputs for the provided pairs are:

• (1, 2): 1 >= 2*2 is 1 >= 4 (False) -> НЕТ
• (8, 4): 8 >= 2*4 is 8 >= 8 (True) -> ДА
• (6, -12): 6 >= 2*(-12) is 6 >= -24 (True) -> ДА
• (-5, -5): -5 >= 2*(-5) is -5 >= -10 (True) -> ДА
• (3, 11): 3 >= 2*11 is 3 >= 22 (False) -> НЕТ
• (-10, 12): -10 >= 2*12 is -10 >= 24 (False) -> НЕТ
• (-10, -2): -10 >= 2*(-2) is -10 >= -4 (False) -> НЕТ
• (4, 1): 4 >= 2*1 is 4 >= 2 (True) -> ДА
• (2, 5): 2 >= 2*5 is 2 >= 10 (False) -> НЕТ

The output for the input pair (4, 1) is:

ДА
