#Shell Sort Algorithm

def shellSort(data, length):

gap = length//2

while gap > 0:
for iIndex in range(gap, length):

temp = data[iIndex]

jIndex = iIndex

while jIndex >= gap and data[jIndex – gap] > temp:
data[jIndex] = data[jIndex – gap]

jIndex -= gap

data[jIndex] = temp

gap //= 2

print(data)
