1. Given a Python dictionary that maps keys to values where the Key is a String and the value is an integer, write code to create a reverse dictionary in which each value becomes a key, and the value associated with this new integer key is a list of the strings that originally had the integer as a value. For example:

     "apple"  : 3
     "pear"   : 2
     "cherry" : 3
     "berry"  : 2
     "orange" : 1
   
   --
   New dictionary:
   
      3 : ["apple", "cherry"]
      2 : ["pear", "berry"]
      1 : ["orange"]
