Solution: Group Anagrams
Explore efficient techniques to group anagrams by tracking character frequencies. This lesson helps you implement a frequency mapping approach that reduces time complexity and optimizes storage, enabling you to solve anagram grouping problems effectively during coding interviews.
Statement
Given a list of strings strs, group together all strings that are anagrams of each other.
An anagram is a string formed by rearranging the letters of another string, using all original letters exactly once. For example, “eat”, “tea”, and “ate” are anagrams.
Return a list of groups, where each group contains strings that are anagrams of each other.
Note: The order of the groups and the order of strings within each group does not matter.
Constraints:
Let strs be the list of strings given as input to find the anagrams.
