By moving twice inside the makeRow function, you automatically handle the "every other" logic without needing a complex "beeper-at-last-spot" variable. Common Pitfalls to Avoid Remember that for a row of length 5,

Below is a breakdown of the verified logic and the code structure needed to solve this efficiently. Understanding the Problem
