Sir what is wrong in this code?

#1

#include
#include
using namespace std;
int max_sum( int a[], int n)
{
int M=0,curr_sum=0;
for(int i=0;i<n;i++)
{
curr_sum=curr_sum+a[i];
if(curr_sum<0)
{
curr_sum=0;
}
M=max(M,curr_sum);
}
return M;
}
int main() {
int t;
cin>>t;
while(t>0){

  int  N,a[10000];
  cin>>N;
  for(int i=0;i<N;i++)
  {
	 cin>>a[i];
  }
  cout<<max_sum(a,N)<<endl;
  t--;
}

return 0;

}

@Harshit-Kumar-2577121455897279 you should take your array size as 10^5 as N can be upto 10^5.
