How many times will the following loop execute?

int a = 5;
while (a > 0) {
    System.out.println(a-- + 2);
    if (a % 2 == 0)
        break;
}

Reason — Let's understand the execution of the loop step by step:

Initially, a = 5, so System.out.println(5 + 2); executes, and a is decremented to 4.
Now, a % 2 == 0 is true (since 4 % 2 == 0), so the break statement is executed, exiting the loop.
Since the loop executes only once before breaking, the correct answer is 1 time.
