我的C ++代码错误的CodeForces错了什么？

Question

#include <iostream>
#include<math.h>
using namespace std;

int main()
{
int h1,min1,h2,min2;
cin>>h1>>min1>>h2>>min2;
if(h1==h2 && min1>min2)
    cout<<(24*60)-fabs(min1-min2);
    else if (h1>h2)
        cout<<((fabs((h1-24)+fabs(h2%12))*60))-fabs(min1-min2);
    else if (h2>h1)
        cout<<((h2-h1)*60)-fabs(min1-min2);
}

所有outPut都是正确的，但它在代码强制中说错了我想知道什么是错误的只是CodeForces或者有些东西是unlogic或者Code一般是错的！？
