The title is incorrect: this is the solution for shell sort.

You never generate the last gap value, which must always be equal to 1, because the last step of shell sort is an insertion sort. Try to change from

return number > 1 ? number : nil

to

return number >= 1 ? number : nil

or

return number > 0 ? number : nil
