//https://leetcode.com/problems/number-of-recent-calls/
// Tried for loop, etc.  While loop was the best when dealing with 10000 requests

// Write a class RecentCounter to count recent requests.
// It has only one method: ping(int t), where t represents some time in milliseconds.
// Return the number of pings that have been made from 3000 milliseconds ago until now.
// Any ping with time in [t - 3000, t] will count, including the current ping.
// It is guaranteed that every call to ping uses a strictly larger value of t than before.
