调试了半天也对比了题解还是看不出来代码哪出错了，dalao们帮忙看一下叭

#include <iostream>
using namespace std;
#include <cmath>
int main()
{
    int n=0,duishu=0;
    cin>>n;
    int scores[n][3];
    int sum[n];
    for(int i=0;i<n;i++)
    {
        for(int j=0;j<3;j++)
        {
            cin>>scores[i][j];
            sum[i]+=scores[i][j];
        }
    }
    for(int k=0;k<n;k++)
    {
        for(int m=k+1;m<n;m++)
        {
            if
            (
                (abs(scores[m][0]-scores[k][0])<=5)&&
                (abs(scores[m][1]-scores[k][1])<=5)&&
                (abs(scores[m][2]-scores[k][2])<=5)&&
                (abs(sum[m]-sum[k])<=10)
            )
            {
                duishu++;
            }
        }
    }
    cout<<duishu<<endl;
    system("pause");
    return 0;
}
