+# Python program for implementation of Quicksort Sort
+
+# This implementation utilizes pivot as the last element in the nums list
+# It has a pointer to keep track of the elements smaller than the pivot
+# At the very end of partition() function, the pointer is swapped with the pivot
+# to come up with a "sorted" nums relative to the pivot
+
+
+# Function to find the partition position
+def partition(array, low, high):
+
+	# choose the rightmost element as pivot
+	pivot = array[high]
+
+	# pointer for greater element
+	i = low - 1
+
+	# traverse through all elements
+	# compare each element with pivot
+	for j in range(low, high):
+		if array[j] <= pivot:
+
+			# If element smaller than pivot is found
+			# swap it with the greater element pointed by i
+			i = i + 1
+
+			# Swapping element at i with element at j
+			(array[i], array[j]) = (array[j], array[i])
+
+	# Swap the pivot element with the greater element specified by i
+	(array[i + 1], array[high]) = (array[high], array[i + 1])
+
+	# Return the position from where partition is done
+	return i + 1
+
+# function to perform quicksort
+
+

+	if low < high:
+
+		# Find pivot element such that
+		# element smaller than pivot are on the left
+		# element greater than pivot are on the right
