What does the command `clearAllBeepers()` accomplish?

The command clearAllBeepers() is specifically designed to remove all beepers that are present on the grid, regardless of Karel's current position. When executed, this command scans the entire environment and eliminates every beeper, allowing Karel to operate in a clean space without any obstructions caused by prior beeper placements.

Understanding this function is important in programming with Karel, as it enables effective management of beeper resources throughout the grid. This command is distinct from other options that either relate to movement, resetting the grid, or placing beepers. Those options would not accurately reflect the role of clearAllBeepers(), which focuses solely on the removal of beepers.
