Question

;;CSE 1302 J;Fall 2014;Lab 8;Recursion in array handling;? Iterative Linear Search (given);? Recursive Linear Search;? Add recursive linear search logic to linearSearchR;? Make case 5 in main a call linearSearchRec.;? Iterative Binary Search;? Add a new method to your IntegerList, called intbinarySearch (int target) which will binary search the array iteratively;? Make case 6 in main a call to binarySearch;? Recursive Binary Search;? Add recursive logic to binarySearchR;? Make case 7 in main a call binarySearchRec;Turn in the final source and output that does the following;? Create an array of 10 positions and print it.;? Search for first item, last item, a middle item in the list, and an item not in list, using linear search, iterative version, case 3;? Search for first item, last item, a middle item in the list, and an item not in list, using linear search, recursive version, case 5;? Now sort the array and print it.;? Search for first item, last item, a middle item in the list, and an item not in list, using binary search, iterative version, case 6;? Search for first item, last item, middle item in the list, and an item not in list, using binary search, recursive version, case 7;Recursive Linear Search;File IntegerList.java contains a class IntegerList that represents a list of integers (you may have used a version of this in an earlier lab), IntegerListTest.java contains a simple menu-driven test program that lets the user create, sort, and print a list and search for an element using a linear search.;Many list processing tasks, including searching, can be done recursively. The base case typically involves doing something with a limited number of elements in the list (say the first element), then the recursive step involves doing the task on the rest of the list. Think about how linear search can be viewed recursively, if you are looking for an item in a list starting at index i;? If iexceeds the last index in the list, the item is not found (return -1).;? If the item is at list[i], return i.;? If the is not at list[i], do a linear search starting at index i+1.;Fill in the body of the method linearSearchR in the IntegerList class. The method should do a recursive linear search of a list starting with a given index (parameter lo). Note that the IntegerList class contains another method linearSearchRec that does nothing but call your method (linearSearchR). This is done because the recursive method (linearSearchR) needs more information (the index to start at) than you want to pass to the top-level search routine (linearSearchRec), which just needs the thing to look for.;// ****************************************************************;// IntegerList.java;//;// Defines an IntegerList class with methods to create, fill;// sort, and search in a list of integers.
