#include <iostream>

if (cx == x && cy == y)

cout << count << endl;

count = 0; cx = 0; cy = 0;

==시간 초과..

#include <cstdio>

int main()

{

int t, m, n, x, y, count, d, cn;

scanf("%d", &t);

while (t--)

{

count = 0;

scanf("%d %d %d %d", &m, &n, &x, &y);

d = m - n; // d=10

for (cn = x; cn > n; cn = cn - n);

count += x; // count=11

while (count <= m*n)

{

if (y == cn)

break;

if (d < 0)

cn = (cn + d > 0) ? cn + d : n + cn + d;

else

cn = (cn + d < n) ? cn + d : cn + d - n;

count += m;

}

(count <= m*n) ? printf("%d\n", count) : printf("-1\n");

}

}

이번엔 틀렸습니다..
