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

pdbq

Sample Output 1

Yes

Sample Input 2

ppqb

Sample Output 2

No

Solution in Python (3.4.3) (judge verdict: Wrong Answer)

s = list(input())
sr = list(reversed(s))
t = len(s)//2
for i in range(t):
    if not (s[i] == "b" and sr[i] == "d" or s[i] == "d" and sr[i] == "b" or s[i] == "p" and sr[i] == "q" or s[i] == "q" and sr[i] == "p"):
        print("No")
        break
else:
    print("Yes")
