Time limits and float tolerances otherwise come from statement.txt; each problem's judge.json has the resolved values. `abs_tolerance` + `rel_tolerance` together mean 'within either bound'. Validators follow the Kattis output-validator protocol (argv: input answer feedback_dir [flags], team output on stdin; exit 42 accept, 43 reject); interactors are wired to the submission over pipes.", |
