        if gap==0:
            gap =1
        swapped = False        for i in range(0, len(arr)-gap):
            if arr[i] > arr[i+gap]:
                swap(arr, i , i+gap)
                swapped = True                print(arr)

def swap(arr, i, j):
    temp = arr[i]
    arr[i] = arr[j]
    arr[j] = temp

combsort(arr)

print(arr)
