Question

Meesho's category team labels a day premium when its order amount reaches at least threshold H. Over n recorded days, they are studying bursts of premium activity and want to count the spans that are just right, contiguous stretches of days containing exactly K premium days, where the remaining days in a stretch may be anything. Two spans are different if they start or end on different days. Given the daily amount, the count K, and the threshold H, report how many contiguous spans contain exactly K premium days.
