Same Letter Cipher

Easy

A simple cipher replaces every character with some other character (or keeps it as is): all occurrences of a character are replaced the same way, and no two different characters may turn into the same one. You are given strings plain and coded of equal length. Return True if coded can be produced from plain by such a cipher, and False otherwise.

Example 1

plain="level", coded="rotor" → True

l→r, e→o, v→t: each letter always becomes the same one and different letters become different ones. True.

Example 2

plain="moon", coded="noon" → False

m→n, but also n→n: two different letters would turn into the same one. False.

Example 3

plain="ab", coded="aa" → False

Constraints

1 ≤ len(plain) ≤ 5·10⁴
len(coded) == len(plain)
Both strings consist of ASCII characters
