using System;

class Program
{
    static String removeChars(String s, String chars) { 
        int i = 0, internal_i = 0; 
        char[] arr = s.ToCharArray(); 
      
        while (i != arr.Length) { 
            char ch = arr[i]; 
            if (chars.ToLower().IndexOf(ch) == -1) { 
                arr[internal_i] = arr[i]; 
                internal_i ++; 
            } 
            i++; 
        }  
         s = new String(arr);
