Debugging is the process of systematically removing errors or bugs from the logic and code of a program. The process of debugging generally involves having a understanding of the intended correct behaviour of the running program and verifying where the actual behaviour of the program diverges from this intended behaviour. While debugging code that works with data structure like lists, trees, arrays, it can be useful to draw these structures visually to understand why something is not working. If task has to be performed multiple times at different locations in code, the code that performs the task needs to be repeated in each of these places.
