Design a hit counter which counts the number of hits received in the past 5minutes. Each function accepts a timestamp parameter (in seconds granularity) and your may assume that calls is being made to the S Ystem in chronological order (ie, the timestamp is monotonically increasing). Assume the earliest timestamp starts at1. It is possible this several hits arrive roughly at the same time. Example:hitcounter counter=Newhitcounter ();//
