Problem Statement: Given two strings s and t, find they are anagrams or not
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"
