❓ Problem Statement

Currently we can fill input in calculator only by clicking with mouse. Keyboard input is not available.

Add keyboard support so the user can operate the calculator using keyboard.

🛠️ Suggested Implementation

Add a keydown event listener to the calculator and map keyboard keys to the existing calculator actions.
