结果正确但超时代吗：

#include<iostream>using namespace std;int main(){    int n;    cin >> n;    int ans = 0;    for(int i = 1; i <= n; i++)    {        for(int j = 1; j <= n; j++)        {            for(int k = 1; k <= n; k++)            {                int t;                int a = i, b = j, c = k;                if(a > b){t = a; a = b; b = t;}                if(a > c){t = a; a = c; c = t;}                if(b > c){t = b; b = c; c = t;}                if(a + b > c && c - b < a && c - a < b)                {                 if(a * a + b * b == c * c) {ans++;}                }            }        }    }    cout << ans / 6 << endl;    return 0;}
