循环改变

#include <bits/stdc++.h>
using namespace std;
#define int long long
int student[5000050];
signed main (){
    int n, p;
    cin >> n >> p;
    for (int i = 1; i <= n; i++){
        cin >> student[i];
    }
    for (int i = 1; i <= p; i++){
        int x, y, z;
        cin >> x >> y >> z;
        for (int j = x; j <= y; j++){
            student[j] += z;
        }
    }
    int minn = 9999999999;
    for (int i = 1; i <= n; i++){
        if (student[i] < minn){
            minn = student [i];
        }
    }
    cout << minn;
}
