1. Use Dry runs to determine algorithm logic

a dry run is a mental run of an algorithm, sometimes expressed in pseudocode, where the computer scientist examines the algorithm's procedures one step at a time. In both uses, the dry run is frequently assisted by a table (on a computer screen or on paper) with the program or algorithm's variables on the top.

2. Retain functional responsibilities

Use local variables instead of instance variables to help retain functional responsibilities.
