To complete the challenge on CodeHS, you must program Karel to fill an empty rectangular world with a beeper pattern resembling a checkerboard. The Strategy
: Ensure Karel ends in a predictable "Home" position if the specific exercise requires it, though most CodeHS auto-graders only check the final beeper pattern.
// Handle multi-row worlds while (leftIsClear()) moveUpAndReverse(); fillRow();
The program must not crash on a 1x1 world or a 1x8 world .
// Check alignment for the West-bound row transition. if (beepersPresent()) if (frontIsClear()) move();
