On this page

Problem Statement:

Two strings are considered similar if you can make one string look like the other using the following two operations:

  1. Swap any two characters.
    • For example, abde -> aedb (e and b swapped).
  2. Replace every occurrence of one character with another, and replace the other character with the first one.
    • For example, acabbb -> bcbaaa (all a's turn into b's, and all b's turn into a's)

Given two strings, word1 and word2, return true if they can be made similar, otherwise return false.
