Problem Statement

Ninja is going to visit her friend Mico. He is thinking to gift her a string. But he came to know that Mico only likes the string 'S'. Ninja already has a string 'K'. Now, Ninja can change the string 'K' in some other string by choosing any character in one move and change all its occurrence with any other lowercase English character. He can do this several times.

Help Ninja to find if he can change his string 'K' to string 'S', which Mico likes.

Note:
Both 'S' and 'K' contain only lowercase English characters.
For Example:
K = "aabb" and S = "bbcc"
Now Ninja can do the following changes:
- Change ‘b’ to ‘c’ -> “aacc”
- Change ‘a’ to ‘b’ -> “bbcc”

Hence Ninja can give Mico the desired gift.
