这是我的代码，已经尝试和题解与std比对了，找不到问题，求问/kk

#include <iostream>
using namespace std;
#define MAX_N 200010
#define int long long
int n,a[MAX_N];
signed main(){
    int t;
    cin >> t;
    while(t--){
        cin >> n;
        for(int i = 1;i <= n;i++)cin >> a[i];
        int start = 0;
        for(int i = 1;i <= n;i++)
            if(a[i] != 0)start = i,i = n + 1;
        // cout << start << endl;
        int x = 0,t = 0;
        for(int i = start;i < n;++i){
            t += a[i];
            if(a[i] == 0)x++;
        }
        cout << t + x << endl;
    }
    return 0;
}
