Given two strings s and t, return true if t is an anagram of s, and false otherwise.
An Anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once.
Example 1:
- input:
s = "anagram", t = "nagaram" - output:
true
Example 2:
- input:
s = "rat", t = "car" - output:
false
