Solution: Group Anagrams
Explore two approaches to group anagrams efficiently: sorting each string as a naive solution and using frequency mapping for an optimized method. Understand time and space trade-offs, and implement hash maps to collect and return groups of anagrams. This lesson helps you develop a strategy to handle anagram problems in coding interviews.
Statement
Given a list of words or phrases, group the words that are anagrams of each other. An anagram is a word or phrase formed from another word by rearranging its letters.
Constraints:
Let strs be the list of strings given as input to find the anagrams.
-
strs.length -
strs[i].length
