LeetCode 242 Valid Anagram

Approach

Check both strings have same length

If they do, run first pass for first string, a second pass for string#2

class Solution {
    fun isAnagram(s: String, t: String): Boolean {
        if(s.length != t.length) return false
        val map = IntArray(26)
        for (c in s) {
            map[c - 'a']++
        }
        for (c in t) {
            if (map[c-'a'] <= 0) return false
            map[c - 'a']--
        }
        
        return true
    }
}
