Your question is Count Peaks in a List. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you count top peaks and bottom peaks in a list of radioactivity values given these rules: top peaks are at least 5 higher than both neighbors, bottom peaks are at least 5 lower than both neighbors, and the first and last items can never be peaks?
