• Process a Task List: Deduplicate, Drop Completed, Sort by Priority, and Nest SubtasksMedium

  Senior backend coding question: process a batch of scheduler tasks by removing duplicates on description and due date, dropping completed tasks, sorting by priority, and placing each subtask directly after its parent. It tests clarifying ambiguous policies, orphan and cycle handling, O(n log n) design, and verified use of an AI coding assistant.

• Propagate Task Filtering Through AncestorsHard

  Design an algorithm to filter a hierarchy of tasks where any task failing a predicate—or having any ancestor that fails or is missing—is excluded along with all its descendants, running in linear time and preserving original order.

• Rank five-card hands by type, then find best and worst completions of unknown cardsMedium

  A two-part coding question on a poker-like card game: compare two five-card hands by a fixed type priority with ties broken card by card, then find the best and worst complete hands when the last cards are unknown. Tests hand classification, ordering keys, testing discipline and search over completions.

• Task Scheduler with Dependencies, Priorities and FiltersMedium

  Coding question that asks for a task scheduler built from a detailed specification: tasks must come after their dependencies, follow priority or importance rules, and pass configurable filters. It tests topological ordering, deterministic tie-breaking, cycle handling and turning many interacting requirements into correct, tested code.
