Solution in C (Clang 3.8.0) (judge verdict: Wrong Answer)

#include <stdio.h>
void Takahashi(int *x, int *y)
{
	if (*x >= 1)
		*x--;
	else if (*y >= 1)
		*y--;
}

int main(void)
{
	int A, B, K, i;
	scanf("%d",&A);
	scanf("%d",&B);
	scanf("%d",&K);

	for(i = 0; i < K;i++)
	{
		Takahashi(&A, &B);
	}
	printf("%d %d", A, B);
	return 0;
