C# Version of the Solution by Yueyi Wang

  • 0
    public class Solution {
        public bool CanConstruct(string ransomNote, string magazine) {
            int[] table = new int[26];
            foreach (var m in magazine) table[m - 'a']++;
            foreach(var n in ransomNote) if(--table[n -'a'] == -1) return false;
            return true;

    How could Java run so much faster than C#? It takes 139ms with this almost identical solution.
