This definitely works and with the space & time complexity you listed. There is a counterintuitive way to solve the problem without the sets you used, instead using the 1st row and 1st column to store the row and columns to zero out. However this is a good solution. Nice work.

Actually I'd say this is O(n) where n is the number of rows or columns in the matrix. You're not building an additional 2D array.
