Nice work, you solved the problem, and you solved it with two external arrays. This definitely works, but you could draw down the memory usage a bit. You can see my inline comments and let me know if you have questions on it.

What do you think the space & time complexities are?

| cols_w_0 = {} | ||

This definitely works, but you could also use the 0th index of the row and columns to serve the same role as the rows_w_0 and cols_w_0 arrays.
