Solution: Similar String Groups
Explore how to solve the Similar String Groups problem by applying Union Find data structures combined with similarity checks between strings. Understand how to identify connected groups based on single swaps and implement efficient solutions while evaluating time and space complexity.
We'll cover the following...
Statement
Two strings x and y are considered similar if they are either exactly the same or can be made identical by swapping at most two different characters in string x.
We define a similarity group as a set of strings where each string is similar to at least one other string in the group. A string doesn't need to be directly similar to every other string in the group — it just needs to be connected to them through a chain of similarities.
Given a list of strings strs, where each string is an anagram of the others, your task is to determine how many such similarity groups exist in the list.
Constraints:
strs.lengthstrs[i].lengthstrs[i]consists of lowercase letters only. ...
