Coding workflows · Union area of two rectangles
03
A concrete starting point
Compute the union area of two axis-aligned rectangles with strictly increasing integer bounds. Check overlapping, contained and touching rectangles, rejecting zero-area or reversed bounds before arithmetic and leaving both inputs unchanged.
Define the change
Describe the input, expected output and boundaries that must stay intact.
Inspect the work
Review the proposed edits and any commands before relying on their result.
Check the outcome
Compare actual behavior with the expected result. If a check fails, investigate it before applying more changes.
