Legacy Thread-Safe Vector Demonstration

Demonstrates the structural operations of a Vector, a legacy collection acting as a synchronized, dynamically resizing array.

Architectural Note: Because all of its core mathematical operations are globally synchronized, Vector incurs a notable thread-locking performance overhead. Modern architectural standards heavily favor unsynchronized dynamic arrays for single-threaded contexts, or specialized concurrent structures for multi-threaded environments.

Complexity

  • Time Complexity:
    • O(1) amortized for appending an element to the tail.
    • O(N) for indexed insertions or value-based removals, as the underlying elements must be shifted in memory.
  • Space Complexity: O(N) to maintain the contiguous backing array, which doubles in capacity upon saturation by default.
