What is the output of the following code snippet? int s1 = 20; if (s1 <= 20) { System. out. print("1"); } if (s1 <= 40) { System. out. print("2"); } if (s1 <= 20) { System. out. print("3"); }

The program outputs 123

Explanation:

The first line of the program initializes s1 to 20

The second line checks if s1 is less than or equal to 20.

This is true,

So, 1 is printed

The third line checks if s1 is less than or equal to 40.

This is true,

So, 2 is printed

The fourth line checks if s1 is less than or equal to 20.

This is true,

So, 3 is printed

Hence, the output is 123
