（原版）
1 #include <cstdio> 2 3 int a, b; 4 5 int C(int x, int y) { 6 int xr = x ^ y; 7 int nd = x & y; 8 while(nd) { 9 int xr1 = xr; 10 int nd1 = nd << 1; 11 xr = xr1 ^ nd1; 12 nd = xr1 & nd1; 13 } 14 return xr; 15 } 16 17 int A(int c) { 18 if(c == a) { 19 return 1; 20 } 21 else { 22 return C(A(C(c, 1)), 1); 23 } 24 } 25 int B(int c) { 26 if(c == b) { 27 return 1; 28 } 29 else { 30 return C(B(C(c, 1)), 1); 31 } 32 } 33 34 35 int main() { 36 while(~scanf("%d %d", &a, &b)) { 37 printf("%d\n", C(A(1), B(1))); 38 } 39 }
然后TLE了
