Question

Quick Sorting In Python​

Answer 1

Answer:

Kindly check proper indentation.

Explanation:

def partition(arr, low, high):

   i = (low-1)

   pivot = arr[high]

   for j in range(low, high):

       if arr[j] <= pivot:

           i = i+1

           arr[i], arr[j] = arr[j], arr[i]

   arr[i+1], arr[high] = arr[high], arr[i+1]

   return (i+1)

def quickSort(arr, low, high):

   if len(arr) == 1:

       return arr

   if low < high:

       pi = partition(arr, low, high)

       quickSort(arr, low, pi-1)

       quickSort(arr, pi+1, high)

if __name__ == "__main__" :

  arr = [10, 7, 8, 9, 1, 5]

  n = len(arr)

  quickSort(arr, 0, n-1)

  print("Sorted array is:")

  for i in range(n):

       print("%d" % arr[i])
