DIY: Group Anagrams
Explore how to group words that are anagrams using Ruby by implementing a function to categorize related words into groups. Understand this real-world coding interview problem to strengthen your problem-solving skills and prepare for technical interviews.
We'll cover the following...
Problem Statement
You are given a list of words or phrases, and you need to group the words that are anagrams of each other. An anagram is a word, phrase, or sentence formed from another word by rearranging its letters.
Input
The input will be a list of words or phrases. The following is an example of input:
["word", "sword", "drow", "rowd", "iced", "dice"]
Output
The output should be a list of grouped words. The following is an example output:
[['word', 'drow', 'rowd'], ['sword'], ['iced', 'dice']]
Coding exercise
You need to implement the function group_anagrams(strs), where strs is the list of words you need to group together. The function returns a list containing multiple lists of the newly created groups.
