Stabilize sliding window anomaly score
Medium Algorithms arena: two pointers, running sums, and window constraints
Log in and clear the lower tiers to unlock this mission.
Missing prerequisites: algorithms-easy-sliding-window-anomaly
Fraud detection needs the shortest window whose score crosses a threshold. You are working inside an algorithm arena, and the arena only clears when the result is safe, deterministic, and explainable.
Learn to apply two pointers, running sums, and window constraints in an algorithm arena while explaining the invariant, safety constraints, and hidden edge cases.
- Demonstrates two pointers, running sums, and window constraints
- 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.
