Given an integer n, return the n rows of an upside-down left-aligned star pyramid — row i has (n − i + 1) stars, shrinking one star per row. This is the Right Half Pyramid, flipped: instead of growing from 1 star to n, it shrinks from n stars down to 1. Both solutions carry the exact same technique over — just with (n − i + 1) in place of i wherever the row length is needed.
