PriorityQueue Demonstration

Demonstrates fundamental operations on a PriorityQueue. This collection is backed by a priority heap data structure, which orders elements according to their natural mathematical ordering (or a specified comparator) rather than their chronological insertion sequence (FIFO).

Complexity

  • Time Complexity:
    • O(log N) for insertion (add) and extraction (poll) as the binary tree structurally rebalances.
    • O(N) for arbitrary value-based removals (remove(Object)), as the structure requires a linear scan to locate the target node before repairing the heap.
    • O(1) for inspecting the highest-priority element at the root (peek).
  • Space Complexity: O(N) to maintain the dynamically resizing contiguous array representing the binary heap.
