Codehs All Answers Karel Top Instant

Trying to write move(); move(); turnLeft(); repeatedly. The "Top" Logic: The spiral decreases step size by 1 after every two turns.

function moveTimes(int n) for(var i = 0; i < n; i++) move();

function moveAndAlternate() while(frontIsClear()) move(); if(ballsPresent()) // If you are on a ball, don't do anything? No. // Actually: Alternating means toggle. // Simpler: Move one step, then putBall if previous had none. codehs all answers karel top

Real answer (short version):

Guessing the pattern. The "Top" Logic: Check every cell. If there is NO ball, put one down. Always move. Trying to write move(); move(); turnLeft(); repeatedly

function start() var row = 1; while (true) for (var i = 0; i < 8; i++) if (row % 2 == i % 2) putBall(); if (i < 7) move(); if (facingEast()) turnLeft(); else turnRight(); row++; if (!frontIsClear()) break; move();

It doesn't matter if the potholes are random or specific. It solves 100% of "row repair" problems. 5. Challenge: "Checkerboard" (The hardest basic Karel) Problem: Cover the entire world (any size) with balls in a checkerboard pattern. A ball on (1,1), no ball on (2,1), ball on (1,2), etc. Real answer (short version): Guessing the pattern
