The sorted values array contains 16 integers 5, 7, 10, 13, 13, 20, 21, 25, 30,32, 40, 45, 50, 52, 57, 60. Indicate the sequence of recursive calls that are made tobinaraySearch, given an initial invocation of binarySearch(32, 0, 15).show only the recursive calls. For example, initial invocation is binarySearch(45,0,15)where the target is 45, first is 0 and last is 15.In JAVA Recursive Array Search. Define and test a recursive method for a sequential search of an integer array. The method should return the index of the searchKey in the array, or return -1 if the searchKey is not found.

When that element is found, it’s swapped with the first element of the array. The process is then repeated for the subarray, beginning with the second element. Each pass of the arrayresults in one element being placed in its proper location. This sort requires processing capabilitiessimilar to those of the bubble sort—for an array of n elements, n – 1 passes must be made, and foreach subarray, n – 1 comparisons must be made to find the smallest value. When the subarray beingprocessed contains one element, the array is sorted. Write a recursive function selectionSort toperform this algorithm
- 8.12 LAB: Binary search Binary search can be implemented as a recursive algorithm. Each call makes a recursive call on one-half of the list the call received as an argument. Complete the recursive method binarySearch() with the following specifications: Parameters: a target integer an ArrayList of integers lower and upper bounds within which the recursive call will search Return value: the index within the ArrayList where the target is located -1 if target is not found The template provides main() and a helper function that reads an ArrayList from input. The algorithm begins by choosing an index midway between the lower and upper bounds. If target == integers.get(index) return index If lower == upper, return -1 to indicate not found Otherwise call the function recursively on half the ArrayList parameter: If integers.get(index) < target, search the ArrayList from index + 1 to upper If integers.get(index) > target, search the ArrayList from lower to index - 1…solve this by c programming Write a program that deletes the first element in an array which matches a search key. Andprint the new array after deletion.Q: Convert this to sorted array #include<iostream> #include"Student.cpp" class StudentList { private: struct ListNode { Student astudent; ListNode *next; }; ListNode *head; public: StudentList(); ~StudentList(); int IsEmpty(); void Add(Student newstudent); void Remove(); void DisplayList(); }; StudentList::StudentList() { head=NULL; }; StudentList::~StudentList() { cout <<"\nDestructing the objects..\n"; while(IsEmpty()!=0) Remove(); if(IsEmpty()==0) cout <<"All students have been deleted from a list\n"; }; int StudentList::IsEmpty() { if(head==NULL) return 0; else return 1; }; void StudentList::Add(Student newstudent) { ListNode *newPtr=new ListNode; if(newPtr==NULL) cout <<"Cannot allocate memory"; else { newPtr->astudent=newstudent; newPtr->next=head; head=newPtr; } }; void StudentList::Remove() { if(IsEmpty()==0) cout <<"List empty on remove"; else { ListNode *temp=head;…
