• Find the Super Admin User Who Can Access Every Camera Through Nested GroupsMedium

  Given permission triples linking users, groups and cameras, find the user who can access every camera through direct ownership or through nested, possibly cyclic group memberships. It tests modeling permissions as a directed graph, reachability that tolerates membership cycles, and edge cases such as an input with no cameras or a group that covers everything.

• Intersect Motion Threshold Periods Across CamerasHard

  Find maximal motion periods for one camera or the simultaneous intersection across many piecewise-constant camera streams. The prompt defines exact integer timestamps, threshold scaling, last-reading horizon, undefined prefixes, inclusive endpoints, and deterministic interval ordering for portable console verification.
