In this programming assignment, you will design and implement a (n) algorithm to use a hash table to determine the most frequently occurring integer in an array of 'n' integers as well as print the associated largest frequency. You are given a singly Linked List-based implementation of a Hash table. You could augment this code to do the assignment. The main function is setup to generate an array of random integers (of size numElements) in the range [1...maxValue]; the hash function is given by K mod hashTableSize where K is an integer data in the array. Submission (in Canvas): Submit Items 1 and 3 together as a PDF file and submit item 2 as a .cpp file 1) Explain of your algorithm and justify that its time complexity is (n) for an array of 'n' integers. 2) The complete C++ code, including the augmentation/changes you made to the assigned code. 3) A screenshot of the output obtained by running the code for numElements = 50; maxValue = 15 and hashTableSize = 7.
