（原版）

#include <cstdio>

int a, b;

int C(int x, int y) {
    int xr = x ^ y;
    int nd = x & y;
    while(nd) {
        int xr1 = xr;
        int nd1 = nd << 1;
        xr = xr1 ^ nd1;
        nd = xr1 & nd1;
    }
    return xr;
}

int A(int c) {
    if(c == a) {
        return 1;
    }
    else {
        return C(A(C(c, 1)), 1);
    }
}
int B(int c) {
    if(c == b) {
        return 1;
    }
    else {
        return C(B(C(c, 1)), 1);
    }
}


int main() {
    while(~scanf("%d %d", &a, &b)) {
        printf("%d
", C(A(1), B(1)));
    }
}

然后TLE了
