Harden first bad build search
Hard Algorithms arena: binary search over a monotonic predicate
Log in and clear the lower tiers to unlock this mission.
Missing prerequisites: algorithms-easy-first-bad-build
A deploy train contains the first build where tests begin failing. You are working inside an algorithm arena, and the arena only clears when the result is safe, deterministic, and explainable.
Learn to apply binary search over a monotonic predicate in an algorithm arena while explaining the invariant, safety constraints, and hidden edge cases.
- Demonstrates binary search over a monotonic predicate
- Handles the visible sample and hidden edge cases
- Keeps output deterministic and explainable
- Avoids unsafe dynamic execution
Clear the route first
You can read the mission brief, but the editor, hints, tests, and submit flow stay locked until progression or plan access catches up.

Run the visible checks when your first pass is ready.
