This problem can be easily solved using properties of deque,below is the implementation of the same:::

#include<bits/stdc++.h>
using namespace std;

int main()
{int a;
    cin>>a;
    while(a--)
    {
        int q,w;
        cin>>q;
        deque<int> dq;
        for(int i=0;i<q;i++)
        { cin>>w;
         dq.push_back(w);
        }
       
        int p=-1;
        int moves=0,alice=dq.front(),alice_total=0,bob=0,bob_total=0;
        alice_total=alice;
        dq.pop_front();

        while(dq.size()>0)
        {
            if(p==-1)//bob turn
            { bob=0;
                while(bob<=alice&&dq.size()>0)
                {
                bob+=dq.back();
                dq.pop_back();
                }
                bob_total+=bob;
                moves++;
            }
            else//alice turn
            {
                    alice=0;
                    while(alice<=bob&&dq.size()>0)
                    {
                        alice+=dq.front();
                        dq.pop_front();
                    }
                        alice_total+=alice;
                    moves++;
            }
             p=p*-1;
        }
              cout<<moves+1<<" "<<alice_total<<" "<<bob_total<<endl;
    }
    
    return 0;
}
