(a) Write a method public static void insert(int[] a, int n, int x) that inserts x in order among the first n elements of a, assuming these elements are arranged in ascending order. Do NOT use arraylists. x is the last element in a. n does not include x. (b) Using the insert method from Part (a), write a recursive implementation of Insertion Sort.

def reverse_list (1st: List [Any], start: int, end: int) -> None: """Reverse the order of the items in list , between the indexes and (including the item at the index). If start or end are out of the list bounds, then raise an IndexError. The function must be implemented **recursively**. >>> lst ['2', '2', 'v', 'e'] >>>reverse_list (lst, 0, 3) >>> lst ['e', 'v', 'i', '2'] >>> lst [] >>>reverse_list (lst, 0, 0) >>> lst [0] >>> Ist = [] >>> reverse_list (lst, 0, 1) Traceback (most recent call last): IndexError #1 #1
Exercise G -- Implement a function halves that takes a list of integers and divides each element of the list by two (using the integer division operator //) NOTE use the map function combined with a lambda expression to do the division with a neat solution halves : List Int -> List Int halves xs = [ ] --remove this line and implement your halves function here
Code you provide code in python?
in java pls and thank you!
Implement bubble sort, selection sort iteratively, and recursively. Implement linear search. Familiarize with C++ STL class vector Program Execution: The following example illustrates how your program should work. The program first reads the length of the vector (as 5 in example below), then reads this number of integers, and push them into a vector. The program then reads a command (selection, bubble, rselection, rbubble), and call the corresponding sorting function to sort the vector. The vector after being sorted will be displayed. Note that the user input are underscored. [storm:]$ g++ lab1.cpp -o lab1.exe [ storm:]$ ./lab1.exe 5 74 25 32 99 24 selection 24 25 32 74 99 [storm:]$ ./lab1.exe 317 5 23bubble 5 17 23 General Hints:* Write your main function first. * Incrementally write one function and test it before moving to the next. Please refer to the slides on how to implement these functions. 1. selection: iterative selection sort function bubble: iterative bubble…
Practice recursion on lists Practice multiple base conditions Combine recursion call with and,or not operators Search for an element in a list using recursion Instructions In this lab, we will write a recursive function for searching a list of integers/strings. Write a recursive function to determine if a list contains an element. Name the function recursive_search(aList, value), where aList is a list and value if primitive type is the object we want to search for. Return a boolean, specifically True if and only if value is an element of aList else return False from the function Examples: recursive_search([1,2,3], 2) == True recursive_search([1,2,3], 4) == False recursive_search([ ], 4) == False recursive_search([ [ 1 ], 2 ], 1) == False # -----> (because the list contains [ 1 ] and 2, not 1) Hint: Think about what the base case is? When is it obvious that the element is not in the list? If we are not at the base case, how can you use the information about the first element of the…
Write a function with the signature below that returns the sum of the last k elements of a singly linked list that contains integers. int returnSumOfLastKNodes(Node* head, int k) Example: 10 -> 5->8->15->11->9->23 10 represents the head node, returnSumOfLastKNodes(Node* head, 4) will return 58.
