Valid Anagram

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. ### Constraints - `1 <= s.length, t.length <= 5 * 10^4` - `s` and `t` consist of lowercase English letters. ### Input Format Two space-separated strings `s` and `t` on a single line. ### Output Format Print `true` if `t` is an anagram of `s`, otherwise `false`.
