205. Isomorphic Strings[E]

https://leetcode.com/problems/isomorphic-strings/

Description

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:

1
2
Input: s = "egg", t = "add"
Output: true

Example 2:

1
2
Input: s = "foo", t = "bar"
Output: false

Example 3:

1
2
Input: s = "paper", t = "title"
Output: true

Note:
You may assume both *s* and *t* have the same length.
