205. Isomorphic Strings

Given two strings s and t, determine if they are isomorphic.

Two strings are isomorphic if the characters in s can be replaced to get t.

All occurrences of a character must be replaced with another character while preserving the order of characters. No two characters may map to the same character but a character may map to itself.

Example 1:

Input: s = "egg", t = "add" Output: true Example 2:

Input: s = "foo", t = "bar" Output: false Example 3:

Input: s = "paper", t = "title" Output: true Note: You may assume both s and t have the same length.

        return list(map(s.find,s))==list(map(t.find,t))
