Solve Anagram Without Sorting
Problem Description
Given two strings, s and t, determine if t is an anagram of s. An anagram is formed by rearranging the letters of a different word or phrase, using all the original letters exactly once. You are explicitly forbidden from sorting either string.
Constraints
- Both strings
sandtwill contain only lowercase English letters.
Examples
s = "listen",t = "silent"->trues = "rat",t = "car"->false
Follow-up
Can you solve this problem in linear time complexity using a hash table or a frequency-count approach?
