#include <iostream>
using namespace std;

int bitManipulation1(int n, int m, int i) {
    return ((m>>i)&1) == 1?  (n|(1<<i)) : (n&(~(1<<i)));  //注意格式
    }

int main() {
    int n, m, i, t;
    cin >> t;
    while (t--) { 
        cin >> n >> m >> i;
        cout << bitManipulation1(n, m, i) << endl;
    }
    return 0;
