This idea uses a hash table to record the times of appearances of each letter in the two strings s and t.For each letter in s, it increases the counter by 1 while for each letter in t, it decreases the counter by 1.Finally, all the counters will be 0 if they two are anagrams of each other.. It is equal to complexity taken by sorting. Given two strings s and t , write a function to determine if t is an anagram of s. Note: FACEPLANT created at: 16 hours ago | No replies yet. return false; In the end, if the hashmap is empty, we know they are anagrams. Related Topics.
