Consider the following code. #include int main() { int n, i, s = 0; scanf("%d", &n); for (i = 2; i < n; i++) { if (n % i != 0) { continue; } s += i; } printf("%d", s); return 0; } Let the input is a positive integer in the given program. What does the code do?

(A) Calculates the sum of all factors of input integer n (excluding 1 and n).

(B) Calculates the sum of all non-factors of input integer n between 1 and n.

(C) Calculates the sum of all odd value factors of input integer n (excluding 1 and n).

(D) Calculates the sum of all even value factors of input integer n (excluding 1 and n).
