问题标题: 酷町堂：1030 景区观光 代码找错

//CODE
//#pragma GCC optimize(3)

#include <iostream>
#include <cmath>
#include <cstdio>
using namespace std;
int n;
double x, y;
int s;

int main() {
//  freopen ("题目名.in", "r", stdin);
//  freopen ("题目名.out", "w", stdout);
    cin >> n;
    for (int i = 1; i <= n; i ++) {
        cin >> x >> y >> s;
        double jl = sqrt(x * x + y * y);
        ans += (jl / 5) * 2 + s * 15;
    }
    cout << (int)(ans + 0.5);
//  fclose (stdin);
//  fclose (stdout);
    return 0;//好习惯！
}
