7. Consider using "in place" (i.e. no extra space used) quicksort and always taking the last element as pivot to sort the list 9,5,4,8,2,0,7,6. (a) What are the input parameters to the first three recursive calls to quicksort (i.e. exclude the initial call, which is quicksort(list, 0,7) )? (b) What is the state of the list right before the fourth recursive call to quicksort? Make sure to use the algorithm presented in class..
