TELEPHONE BOOK USING HASHMAP

  Sample Input 3 sam 99912222 tom 11122222 harry 12299933 sam edward harry Sample Output sam=99912222 Not found harry=12299933 Explanation We add the following    (Key,Value)  pairs to our map so it looks like this: We then process each query and print  key=value  if the queried   is found in the map; otherwise, we print  Not found . Query 0:   sam Sam is one of the keys in our dictionary, so we print  sam=99912222 . Query 1:   edward Edward is not one of the keys in our dictionary, so we print  Not found . Query 2:   harry Harry is one of the keys in our dictionary, so we print  harry=12299933 . SOLUTION: package   H acker R ank_problems . practice_problems ; import   java . util .*; import   java . io .*; public   class   TelephoneBook {      public   static   void   main ( String  [] argh ){          Scanne...
