Part 2: Unroll Write a function called unroll, which takes in a square array of arrays (i.e. a grid with n rows and n columns). An input could look like this: const square = [ [1, 2, 3, 4], [5, 6, 7, 8], ]; [9, 10, 11, 12], [13, 14, 15, 16] unroll should take in such a square array and return a single array containing the values in the square. You should obtain the values by traversing the square in a spiral: from the top- left corner, move all the way to the right, then all the way down, then all the way to the left, then all the way up, and repeat. For the above example, unroll should return [1, 2, 3, 4, 8, 12, 16, 15, 14, 13, 9, 5, 6, 7, 11, 10].
Assignment #6 - Array Practice Due: Wed, Nov 16 Objective To gain practice with arrays and common array algorithms, as well as the use of array parameters in functions. Task This assignment will consist of writing several functions that manipulate arrays or access data from arrays, as well as a test program that will allow interactive testing of the array functions. Part 1: Functions Write the following functions. Each one takes in an integer array as a parameter, and other necessary parameters are returns are described. Make sure the parameters are in the order specified. Make sure to use the const qualifier on the array parameter on any function where it is appropriate. A sample CALL is given for each function. • Insert Write a function called Insert that takes in four parameters: o an integer array o the size of the array o the new value to be inserted into the array o the index at which to insert the new value This function should insert a a new value into the array, at the…
Read in an integer n (n < 25). Read n integers in an array A. Then do the following (writeseparate programs for each, only the reading part is common).a) Find the sum of the absolute values of the integers.b) Copy the positive and negative integers in the array into two additional arrays B and Crespectively. Print A, B and C.c) Exchange the values of every pair of values from the start (so exchange A[0] and A[1],A[2] and A[3] and so on). If the number of elements is odd, the last value should stay thesame.

Implement an empty integer array of capacity 5. a) Use a loop to input values from the console into the array. b) Use a loop to determine the smallest element in the array. c) Use a loop to determine the largest element in the array. d) Use a loop to output the array. e) Output the smallest and largest elements. Example Output [0] = 4 [1] = 24 [2] = 123 [3] = 54 [4] = 3 Array: 4 24 123 54 3 Max: 123 Min: 3 programming language is c++ pleasw do it in a easy way
4. Arrays. In order to test the functions in this question, you will need an array. We can create a three- dimensional test array as follows: testArray xijk - máx rij,k i=1 i=1 i=1 (b) Now suppose we want a function testFn2 which returns the d2 x d3 matrix {zj.k} where di Zj,k = Σ i=1
