Given the following Hash Table implementation, write the put() method. public class Linear ProbingHashST { } private int M = 30001; private Value [] vals = (Value []) new Object [M]; private Key [] keys = (Key []) new Object [M]; private int hash (Key key) public void put (Key key, Value val) {...} public Value get (Key key) { } for (int i=hash (key); keys [i] != null; i = (i+1) % M) if (key.equals(keys [i])) return vals[i]; return null;
