/** * Lays beepers on odd-numbered streets starting at the first corner. * Pre-condition: Karel is at the start of an odd-numbered street, facing east. * Post-condition: Karel is at the east end of the street, facing east. */ private void layOddStreet() putBeeper(); while(frontIsClear()) move(); if(frontIsClear()) move(); putBeeper();

The pattern must continue correctly when Karel moves from the end of one row to the start of the next.

Using while(frontIsClear()) for the row and while(leftIsClear()) (or rightIsClear() depending on the direction) for the vertical progression ensures the code works for , , or worlds. Key Logic Considerations

However, I don’t have access to a verified answer key for problem “645” from any specific curriculum. If you can provide:

Always test your code on the 1x1 world and the 8x2 world in CodeHS to ensure your solution is truly universal!
