📘 Welcome to Part 223 of Code & Debug’s DSA in Python Course!
In this video, determine whether two strings are anagrams by verifying equal character frequencies. The optimal solution uses a frequency map (or fixed 26-length array for lowercase) to count in s and cancel in t in linear time; an alternative is sorting both strings and comparing, at O(n log n). We’ll implement both and discuss Unicode handling.
