(40 points) Write another Java program called CountingSort that takes an input array [50, 11, 33, 21,40,50,40,40,21] and generates an output array [11, 21, 21, 33, 40, 40, 40, 50, 50]. Users might also give any input arrays. Test your program with different testcases. Below is the basic introduction on Counting sort: In computer science, a sorting algorithm is an algorithm that puts elements of a list into an order. Below is how the input array is represented ARRAY [ ] =[50,11,33,21,40,50,40,40,21]. Below is the expected output after sorting ARRAY [] =[11,21,21,33,40,40,40,50,50]. ATTN : You can use online resource to figure out how a sorting algorithm works. Please be reminded that you cannot use library functions to sort. Doing so will result in a score of Zero
