this problem can be solved using deque easily. below is the code::: ______________________________________________________________________________________________________________

include<bits/stdc++.h>

using namespace std; int main() {int a; cin>>a; while(a--) { int q,w; cin>>q; deque 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();

// cout<<"bob "<<bob<<" ";
            dq.pop_back();
            }bob_total+=bob;
            moves++;
        }
        else//alice turn
        {
                alice=0;
                while(alice<=bob&&dq.size()>0)
                {
                    alice+=dq.front();
                    // cout<<"alice "<<alice<<" ";

                    dq.pop_front();
                }

                    alice_total+=alice;
                moves++;
        }
         p=p*-1;
    }
          cout<<moves+1<<" "<<alice_total<<" "<<bob_total<<endl;
}


return 0;
