Please use Python and don't make the code overly complicated and lengthy. Thanks.

 

Create a KeyIndex class with the following properties : 

 

Fields: 

 

int [ ] k; 

 

Description

An array of integers. 

 

Note: You can maintain another instance variable if needed (but you can’t use more than one).

 

Constructor:

KeyIndex(int [ ]a)



Description:



This constructor takes an array of integers a and populates array k with the element in a as indices into k.

 

Note: make sure the build-up of your array k supports negative and non-distinct integers.

Methods:

 

search (int val)   

Description:

This method searches for the value val within the array and returns true if found or false otherwise.

 

sort ()           

Description:

 

This method will return the sorted form of the array that had been passed into the constructor.

NOTE: Create a tester class or write tester statements to check whether the methods in your KeyIndex class work properly
