Given two strings s and t, determine if they are isomorphic. https://en.wikipedia.org/wiki/Isomorphism https://leetcode.com/problems/isomorphic-strings/description/

Two strings s and t 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.

>>> is_isomorphic("egg", "add")
True
>>> is_isomorphic("foo", "bar")
False
>>> is_isomorphic("paper", "title")
True
>>> is_isomorphic("ab", "aa")
False
