#include
using namespace std;
main()
{
int ts;
cin>>ts;
int a[100];
int k = 0;
int ms;
while(ts–)
{
int n;
cin>>n;
int arr[n];
int k = 0;
int cs;
int ms = 0;
for(int i = 0 ; i < n ; i++)
{
cin>>arr[i];
}
for(int i = 0 ; i < n ; i++)
{
cs = arr[i];
for(int j = i + 1 ; j < n ; j++)
{
cs = cs + arr[j];
if(cs > ms)
{
ms = cs;
}
}
}
a[ts] = ms;
}
for(int i = ts ; i >= 0 ; i–)
{
cout<<a[i];
}
}
