## Problem Statement

You are given four positive integers `rows`, `cols`, `rStart`, and `cStart`. You start at cell `(rStart, cStart)` in a grid of size `rows x cols`. The grid's top-left corner is at `(0, 0)` and the bottom-right corner is at `(rows-1, cols-1)`. 

You need to visit every cell of this grid by walking in a **clockwise spiral pattern**. If you move outside the grid's boundaries, you continue walking outside but will return to the grid later. 

Return an **array of coordinates** representing the order of cells visited during this walk.
