Absolutely, below is a Python function called create$\_$staircase that attempts to form a staircase out of the numbers in the input list, and returns False if it can$$t$.$

Each iteration of the while loop fills one step of the staircase, with the progress of the staircase tracked within the subsets variable. So the first iteration fills the subsets list with $[1],$ the second iteration adds $[2,3]$ to the subsets list, and so on$.$
