只有样例过了

大佬们求调~~~

#include<iostream>
#include<algorithm>
#define int long long

using namespace std;

int q[100100];

signed main()
{
	int n;
	cin >> n;
	
	int l = 0, r = 0, res = -1e7;
	for(int i = 1; i <= n; i++)
	{
		cin >> q[i];
		l+=q[i];
		r = min(l,r);
		res = max(l-r,res);
	}
	
	cout << res;
	
	return 0;
	
}
