Revise: Inputs, Processes, and OutputsBefore writing an algorithm, establish what information the solution needs, what work it must perform and what result it should produce. These are its inputs, processes and outputs, often shortened to IPO.

Check that your inputs provide all the information needed for your processes, and that your outputs answer the stated problem.
