C :

#include<string.h>
#include<stdio.h>
int main()
{char a[10000];
int n,i,j,k,m;
scanf("%d",&n);
while(n--){
int a,b;
scanf("%d%d",&a,&b);
if(b%(a+1)==0) printf("Xiaohong\n");
else printf("Xiaoming\n");
}
}

C++ :

#include <stdio.h>
#include <iostream>
#include <fstream>
using namespace std;
int main(void)
{
//    ifstream cin;
//    ofstream cout;
//    cin.open("i.in");
//    cout.open("i.out");
    int n;
    cin>>n;
    while(n--)
    {
        int m,x;
        cin>>m>>x;
        if(x%(m+1)==0)
            cout<<"Xiaohong"<<endl;
        else
            cout<<"Xiaoming"<<endl;
