🧠 Before you code — what pattern fits?
Two strings are "close" if you can transform one into the other using: (1) swap any two existing characters, or (2) transform every occurrence of one existing character into another existing character, and vice versa.
Given two strings word1 and word2, return true if they are close.
("abc","bca") → true
("a","aa") → false
("cabbba","abbccc") → true
