Avoid forcing this pattern when:
- Need sorted iteration of all elements: Heap doesn't provide sorted order directly. Sort the array if you need all elements in order.
- Need random access or search: Heap only provides access to root. Use hash map or BST for arbitrary element access.
- Fixed small k: For small k (like or ), simple tracking with variables is simpler than heap. Remember: forcing a pattern where it doesn't fit leads to overcomplicated solutions.
If you find yourself fighting the approach, step back and reconsider whether another technique works better.
