Follow the sequence of steps below. The mod operator is the mathematical modulo, which com- putes the integer remainder of divisions. For example 5 mod 2 is 1, 6 mod 2 is 0, 12 mod 5 is 2, etc.

What is the answer when the input x is 5?

1. Input: x 2. Let y=0 3. Repeat for i=1,...,x

(a) If (i mod 2) is 0: i. Yes: do nothing

ii. No: y=y+i

4 . The answer is y
