numbers = (59, 54, 55, 56, 15, 33, 61, 87, 93) Partition(numbers, 0, 5) is called. Assume quicksort always chooses the element at the midpoint

numbers = (59, 54, 55, 56, 15, 33, 61, 87, 93)

Partition(numbers, 0, 5) is called.

Assume quicksort always chooses the element at the midpoint as the pivot.

What is the pivot?

What is the low partition?

What is the high partition?

What is numbers after Partition(numbers, 0, 5) completes?

===============================

This bellow is similar, but I keep getting it wrong with the arrangement of the numbers.

numbers = (18, 32, 42, 47, 13, 44, 49, 85, 62) Partition(numbers, 0,5) is called. Assume quicksort always chooses the element at the midpoint as the pivot. What is the pivot? 42 What is the low partition? 13,18,32 (comma between values) What is the high partition? 42,47,44 What is numbers after Partition(numbers, 0,5) completes? 13,18,32,42,47,44,49,85,62 3 5 Check Next * Each incorrect answer is highlighted. Expected: pivot: 42 low: 18, 32, 13 high: 47, 42, 44 numbers: 18, 32, 13, 47, 42, 44, 49, 85, 62 The midpoint is 0 +(5-0)/2 = 0 + 2 = 2, so the pivot is numbers[2], which is 42. Since 42 is equal to the pivot and 13 is less than the pivot, the partitioning algorithm swaps 42 and 13 to place 13 in the low partition and 42 in the high partition. numbers is now: (18,32, 13, 47, 42, 44, 49, 85, 62) The low partition has elements from index 0 to index 2: (18,32, 13). The high partition has elements from index 3 to index 5: (47, 42, 44). After Partition(numbers, 0,5) completes, numbers is (18, 32, 13, 47, 42, 44, 49, 85, 62)
