Extracted text: Write applications that perform the following: 2.1 Write a program that merges two ordered-list objects of integers into a single ordered list object of integers. Use the merge method of class ListMerge to receive references to each of the list objects to be merged and return a reference to the merged list object. 2.2 Binary search is an important algorithm used to efficiently locate a target value within a sorted sequence of n elements stored in an array. This is among the most important of computer algorithms, and it is the reason that we so often store data in sorted order. This algorithm can be implemented using both the repetition approach and the recursion approach. In this question, you are required to write two applications to perform the binary search using both the repetition approach and the recursion approach to determine the position of the number 15 in the array made of all multiple of 5 less than 100. 2.3 Write an application using a hash table that finds all the pairs of two integers within the below array that add up to 12. Array = {4,9,6,13,5,3,2,8}
