4. Write a program to find kth smallest element in unsorted array?You are given an unsorted array of numbers and k, you need to find the kth smallest number in the array. Forexample if given array is {1, 2, 3, 9, 4} and k=2 then you need to find the 2nd smallest number in the array,which is 2.
6. Write a function that accepts an array of integers and returns -1 if sorted in ascending order, 1 if sorted in descending order, and 0 if not sorted. To be as efficient as possible, your function should make only one pass through the array.
3. Write a program to find intersection of two sorted array.For example, if the two sorted arrays as input are {21, 34, 41, 22, 35} and {61, 34, 45, 21, 11}, it should returnan intersection array with numbers {34, 21}. For the sake of this Problem, you can assume that numbers ineach integer array are unique.

Help me please. Asap. I will give thumbs up. Write a C++ program segment that will perform Bubble Sort Method in sorting the elements of Array B in ascending order where array B is declared as follows :int B[5] = { 5, 4, 1, 3, 2 } ;(Start the comparison from the last 2 elements ofthe array)
Given these two arrays, char arrA[] = {'a', 'e', 'i', 'o', 'u'} and char arrB[] = {'T', 'A', 'B','L','E'}, merge these two arrays into a new array. Make sure that the contents of arrA is interspersed with contents of arrB.
C++ We have an array (x) of ints: x = {6,2,3,1,6,1,1,7,8} We would like to write a void function, call it newArray, that will update the array so that an element of the array is updated by subtracting the first item to its right that is equal to or less than that element. For example, x = {6,2,3,1,6,1,1,7,8] becomes x{4,1,2,0,5,0,1,7,8} Print the updated array, the sum of the array, and a list of the positions of the items that are not updated. *think of nested loops and the use of the break statement where appropriate
