The problem

Two strings are anagrams when one is the other with its letters shuffled: the same letters, each used the same number of times. Return whether t is an anagram of s.

Example

Input:  s = "dusty", t = "study"
Output: true

Constraints

  • 1 <= s.length, t.length <= 5 * 10^4
  • s and t consist of lowercase English letters only, no spaces

How it's graded

  • Run checks your code against the examples. Submit also runs a hidden suite in four groups - basic cases, edge cases, random inputs and performance tests at the size limit - and shows which groups pass, never the hidden inputs.
  • Stuck? Hints come in four steps, from a nudge to a code skeleton, each costing part of the points.
  • Once you pass, you see the approaches from brute force to optimal, and where your solution lands among them.
