Sharing iP code quality feedback [for @WeeJean] - Round 3

[soc-se-script]

@WeeJean We did an automated analysis of your code to detect potential areas to improve the code quality. We are sharing the results below, so that you can avoid similar problems in your tP code (which will be graded more strictly for code quality).

IMPORTANT: Note that the script looked for just a few easy-to-detect problems only, and at-most three example are given i.e., there can be other areas/places to improve.

Suggestion: Consider applying SLAP (and other abstraction mechanisms) to shorten methods e.g., extract some code blocks into separate methods. You may ignore this suggestion if you think a longer method is justified in a particular case.
