Valid Anagram
Last updated
What is Valid Anagram?
Given two strings, decide if one is an anagram of the other, meaning both contain the exact same characters with the same frequency. The trick is not to sort (which works but is slower), but to count character frequencies using a hash map and compare them. This problem teaches you to think about strings as frequency distributions rather than sequences of characters.
