LeetCode 933 | Number of Recent Calls | Queue + Sliding Window | Python Solution | Nidhi Chouhan

Описание: In this video, we solve LeetCode 933 – Number of Recent Calls using Queue (deque) and the Sliding Window technique.

We implement a RecentCounter class where:

Each incoming request ping(t) is stored in a queue.

Old requests outside the last 3000 milliseconds are removed.

Finally, we return the number of valid recent calls.

This problem is a perfect example of combining Queue data structure with the Sliding Window technique.

🔑 Concepts Covered:

Queue Data Structure (FIFO)

Sliding Window Technique

Deque operations in Python (append, popleft)
