哪里错了帮忙看看，为啥百分之0%啊。#include #includeusing namespace std;int main() {    int n; cin>>n;    int a;    int b;    long cnt = 0;    long res = 0;    for(int i=0;i cin>>a>>b;        if(a            swap(a, b);        }        int c = a/b;        int d = a%b;        if(d/(b+0.0f)            cnt--;            d = d + b;             }         if(b>d){            res += (b - d);        }        else{            res += (d - b);        }        cnt += c;    }    cout    cout}
