You are given an array of strings, you need to group the anagrams. Two strings are said to be anagrams if they have the exact same characters with the same frequency. The placement can change though. Watch this video to learn 2 methods to solve this problem. We will take advantage of properties of anagrams and use it in our favor. At the end we will see a dry-run of the code to see what is actually happening behind the scenes. 00:00 - Intro 01:12 - Problem statement and description 04:40 - Method 1: Categorize by Sorting 09:03 - Method 2: Categorize by Frequency 13:09 - Dry-run of Code 15:44 - Generate Frequency String 18:09 - Final Thoughts 📚 Links to topics I talk about in the video: Brute Force Algorithm:    • Brute Force algorithms with real life exam...   Sorting Techniques:    • Sorting Techniques   Time Complexity:    • What is the Time Complexity of an Algorith...   What is Big O?:    • Big O Notation Simplified to the MAX | Stu...   📘 A text based explanation is available at: https://studyalgorithms.com/string/le...
