OutputFor each test case, output two numbers A and B – the number of frog and the number of chicken.
Sample Input Sample Output1 #include<cstdio> 2 #include<iostream> 3 using namespace std; 4 5 int main() 6 { 7 int T; 8 int n,m,a,b; 9 scanf("%d",&T); 10 while(T--) 11 { 12 scanf("%d%d",&n,&m); 13 a=(m-2*n)/2; 14 b=n-a; 15 printf("%d %d\n",a,b); 16 } 17 return 0; 18 }
