a). Consider an array of integers consisting of the number: 12 8 32 19 92 89 90 45 67 55 72. Suppose the pivot is the last element in the list i.e. integer 72. Apply just the partition algorithm of Quick Sort method on this list and show the list after each swap of the elements. At the end, show the resulting low partition and high partition. b). Consider an array of integers consisting of the number: 12 8 32 19 92 89 90 45 67 55 72. Apply the radix sort to the list. Explain the process and show all the intermediate work that leads to the sorted list
