Identify grid crossovers in an operations matrix. A grid crossover is a cell whose value is greater than or equal to every value in its row and less than or equal to every value in its column.

Grid Crossovers
Step 1
Clone the starter repo
Candidate gets the full project locally — README, source, tests, runner config.
Step 2
Run the visible tests
Public test file is right there. Expectations are explicit from minute one.
Step 3
Make tests pass, push
Candidate works in their own style, pushes reviewable commits for your team.
