>I find single file dense leetcode style code easier to understand

I find it really difficult to go through huge chunks of iterative code. I need abstractions otherwise I can't get my head around it. I often wind up refactoring into manageable chunks (even in pseudocode/diagrams) just so I can understand stuff.

For reference, my cognitive abilities are heavily skewed towards verbal/abstract reasoning - like several standard deviations above the norm - and my spatial/concrete reasoning is nearly the inverse of this, it's terrible.

I wonder if this has something to do with it!
