Write a function that takes an array Arr of size N and returns another array which, first disregards the numbers greater than a certain threshold (also a passed parameter), and then stores the remaining elements of the array Arr first in an increasing order and then in a decreasing order Example: If Arr = {5,4,1,12,0,2} and threshold = 10, the returned array should be = {0,1,2,4,5,5,4,2,1,0} In the main method, the user is asked to enter the size of array Arr, the value of the threshold, as well as all the elements of array Arr.
