Group Anagrams Together

Given an array/list of strings STR_LIST, group the anagrams together and return each group as a list of strings. Each group must contain strings that are anagrams of each other.

Example:

STR_LIST = ["abc", "ged", "dge", "bac"]

Output:

[ ["abc", "bac"], ["ged", "dge"] ]

Explanation:

The words "abc" and "bac" are anagrams, so they form one group, and "ged" and "dge" form another group.

Constraints:

Question

Group Anagrams Together

Given an array/list of strings STR_LIST, group the anagrams together and return each group as a list of strings. Each group must contain strings that are anagrams of each other.

Example:

STR_LIST = ["abc", "ged", "dge", "bac"]

Output:

[ ["abc", "bac"], ["ged", "dge"] ]

Explanation:

The words "abc" and "bac" are anagrams, so they form one group, and "ged" and "dge" form another group.

Constraints:

1 <= T <= 5
1 <= N <= 1000
1 <= |STR_LIST[i]| <= 100
STR_LIST[i] contains only lowercase English letters.

Note:

An Anagram is a word or phrase formed by rearranging the letters of a different word or phrase.

Input:

The first line contains an integer 'T', the number of test cases.
Each test case starts with an integer 'N', the number of strings.
The following line contains 'N' space-separated strings.

Output:

For each test case, print the anagram groups with each group in a separate line.

Accepted Answer

Group anagrams in a list of strings together and return each group as a list of strings.

Iterate through the list of strings and sort each string alphabetically to identify anagrams.
Use a hashmap to group anagrams together based on their sorted versions.
Return the values of the hashmap as the grouped anagrams.
