Problem Statement

You are given a string S consisting of letters b, d, p and q.
Determine whether S is a mirror string.

Here, a mirror string is a string S such that the following sequence of operations on S results in the same string S:

Reverse the order of the characters in S.

Replace each occurrence of b by d, d by b, p by q, and q by p, simultaneously.

Constraints

1 \leq |S| \leq 10^5

S consists of letters b, d, p, and q.

Input

The input is given from Standard Input in the following format:

S

Output

If S is a mirror string, print Yes. Otherwise, print No.

Sample Input 1

Sample Output 1

Yes

Sample Input 2

#include<bits/stdc++.h>
using namespace std;
int main()
{
    string a;
    cin>>a;
    string b=a;
    reverse(a.begin(),a.end());
    for(int i=0;i<a.size();++i)
        if (a[i]=='b') a[i]='d'; else
            if (a[i]=='d') a[i]='b'; else
                if (a[i]=='p') a[i]='q'; else
                    if (a[i]=='q') a[i]='p';
    if (a==b) printf("Yes"); else printf("No");
