Show the operation of Quicksort (non-randomized) on the array [19,17,15,13,11,7,5]. You must show the following for each call made to Partition: a. The values of p and r b. The pivot chosen c. The state of array A after the call to Partition completes. For example, for the first call to Partition: p=1,r=7,pivot=5,A=[5,17,15,13,11,7,19]
