问题

为什么代码过不了p1115，我看和别人没什么区别

代码

#include<iostream>
#include <algorithm>

using namespace std;

int dp[200000],a[200000],ans=-INT_MAX;

int main()
{
   int n;
   cin >> n;
   for (int i = 1; i <= n; i++) {
   	cin >> a[i];
   	dp[i] = max(dp[i - 1] + a[i], a[i]);
   	ans = max(ans, dp[i]);
   }
   cout << ans;
}```
