题意:
You are playing a variation of game 2048. Initially you have a multiset s of n integers. Every integer in this multiset is a power of two.

You may perform any number (possibly, zero) operations with this multiset.

During each operation you choose two equal integers from s, remove them from s and insert the number equal to their sum into s.

For example, if s={1,2,1,1,4,2,2} and you choose integers 2 and 2, then the multiset becomes {1,1,1,4,4,2}.

You win if the number 2048 belongs to your multiset. For example, if s={1024,512,512,4} you can win as follows: choose 512 and 512, your multiset turns into {1024,1024,4}. Then choose 1024 and 1024, your multiset turns into {2048,4} and you win.

You have to determine if you can win this game.

You have to answer q independent queries.

思路:

将不大于2048的加起来判断

代码:

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

int main()
{
    int t, a, b, c;
    cin >> t;
    while (t--)
    {
        cin >> a >> b >> c;
        if (a < b)
            swap(a, b);
        c += (a-b);
        a = b;
        int sum = min(a, c);
        a -= sum, b -= sum, c -= sum;
        cout << sum+(a+b)/3 << endl;
    }

    return 0;
}
