写一个 RecentCounter 类来计算特定时间范围内最近的请求

class RecentCounter {
    int count;
    public RecentCounter() {
        this.count=0;
    }
     Queue<Integer> queue=new LinkedList<>();
    public int ping(int t) {
        int c=0;
          queue.offer(t);
        Queue<Integer> myqueue=new LinkedList<>(queue);
       
      
        while(!myqueue.isEmpty()){
            int x=myqueue.poll();
            if(x>=t-3000&&x<=t) {
                c++;
            }else{
                queue.poll();
            }
        }
        return c;

    }
}

/**
