When NOT to Use

Avoid forcing this pattern

Avoid forcing this pattern when:

  • Need arbitrary access to stack elements: Monotonic stack only provides access to maintained elements. Use different structures for random access.
  • Order doesn't matter: If you just need min/max overall, simple tracking suffices without stack overhead.
  • Relationships aren't based on value comparison: Monotonic stack relies on comparing values.

Other relationships need different approaches.
