How to determine if two strings are anagrams of each other?

Two strings are anagrams if they contain the same characters in the same quantity, but in a different order.

A simple way to check for an anagram:

1. Ensure the strings are of equal length.
2. Sort the characters of both strings.
3. Compare the sorted strings — if they are identical, the strings are anagrams.

Example in Kotlin:

fun areAnagrams(s1: String, s2: String): Boolean {
    if (s1.length != s2.length) return false
    return s1.toCharArray().sorted() == s2.toCharArray().sorted()
}
