Palindrome is a string that is identical to its reverse, like "level" or "aba". Check whether a given string is a palindrome or not. 

// function.h
#include <iostream>
#include <string>

using namespace std;

class PalindromeChecker
{
private:
    static const int MAXWORDLENTH=100001;
    char word[MAXWORDLENTH];//store the input string

public:

    PalindromeChecker();
    PalindromeChecker(const char*);
    PalindromeChecker& operator=(const PalindromeChecker& p);
    void reverse();
    friend bool operator== (PalindromeChecker &p1, PalindromeChecker &p2);

};

main.cpp

// main.cpp
#include <iostream>
#include "function.h"

using namespace std;

int main()
{

    char word[100001];
    while(cin >> word){

        PalindromeChecker p1(word);
        PalindromeChecker p2;

        p2 = p1;

        p2.reverse();

        if(p1==p2)
            cout << "Yes\n";
        else
            cout << "No\n";
    }

    return 0;
}

The input consists of multiple lines. Each line contains a string. The length of each string is less than 100000. The number of test case is less than 1000. 

For each test case, output "Yes" if it's a palindrome or "No" if it's not a palindrome in a line.
