205 - Isomorphic Strings.

Easy

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

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.

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

Constraints:

  • 1 <= s.length <= 5 * 104
  • t.length == s.length
  • s and t consist of any valid ascii character.
