Problem: Group Anagrams

Medium

30 min

Explore how to group a list of strings into anagrams by efficiently tracking character patterns. This lesson helps you understand the problem and apply coding strategies to identify and group all anagram strings correctly. You will learn to handle permutations and improve problem-solving skills relevant to 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.

$1 \leq$ strs.length $\leq 10^3$
$0 \leq$ strs[i].length $\leq 100$
strs[i] consists of lowercase English letters.
