Randomized Select Algorithm

A randomized algorithm is defined as one that uses a certain amount of randomization in its logic or operation. It is said to be an algorithm that depends on the random number to perform its operation. It is used for reducing the overall time complexity, space complexity in the standard algorithm. The randomized algorithm uses the concept of random numbers to find the solutions to the different kinds of problems and also to improve the problem solutions.

Question

100%

You are given the following class definition for an array-based List ADT:
public abstract class List {
protected int [] m_array;
protected int m_index;
the array
public List (int cap) {
}
m_array = new int [cap];
m index
= 0;
public abstract int sum();
// underlying array
// index of the next open slot in

Follow the steps below to create a concrete class EnhancedList with required
instance variables and methods.
1. Make sure that the EnhancedList class inherits from List.
2. Declare two private instance variables: int m_low and int m_high which
are used in one of the methods you are required to implement.
3. Create a constructor that takes two parameters int cap, int low, and int
high.
4. The constructor should call the constructor of the super class and initialize the
instance variable properly.
5. Create a void method rectify () that verifies if each element is with the
range of [m_low, m_high]. If any element is smaller than m_low, change its
value to m_low. Similarly, if any element is greater than m_high, change its
value to m high.
6. Override the sum method so it computes and returns the sum of the elements
on the list. Note: Don't forget to add the @Override keyword!
