How does a hash table achieve average O(1) lookups?

OpenAI

A hash table maps each key to a bucket with a hash function, so a lookup jumps straight to the slot instead of scanning.

Collisions are handled by chaining or open addressing; past a ~0.75 load factor it grows and rehashes.

Average lookup is O(1), degrading to O(n) only when most keys collide.

Claude

The idea: turn a key into an array index in constant time, then keep each bucket small.

A good hash function spreads keys evenly and the table rehashes as it fills — so insert, find and delete are all amortized O(1).

Worst case is O(n) when every key collides, which is why real tables randomize the hash.

An unfair advantage, invisible by design.

Everything you need to walk into any call with an expert whispering in your ear — and no one else in the room knowing it exists.

Overlay mode

Floats over your meeting

A transparent, always-on-top, click-through overlay sits on top of Zoom, Meet, and Teams. Read your answers without ever taking focus off the call.

  • Never steals focus — clicks pass straight through to your meeting
  • Always on top, so answers stay in view while you talk

Screen-share safe

They'll never see it

Hidden from screen sharing and screen recording with one toggle. The interviewer sees a normal shared screen; you see your answers. Technically, the window sets NSWindow.sharingType = .none.

  • Invisible in Zoom / Meet / Teams screen shares and recordings
  • One switch keeps it yours — flip it off anytime

Toggle it — that's exactly what the interviewer sees vs. what you see.

Global hotkeys

Answer without lifting a finger

Every action has a global shortcut that works even while the app is invisible. Snap a coding question off the screen with screenshot + OCR, pause listening, or copy the last answer — all without touching the window.
