How do you check the first element in a Queue<T> without removing it?

Short answer: Use the Peek() method to view the front element without removing it.

Example code

Queue<string> tasks = new Queue<string>(); tasks.Enqueue("Task1"); string nextTask = tasks.Peek(); // Returns "Task1", does not remove it Useful when you want to see what’s next without modifying the queue.

Real-world example (ShopNest)

ShopNest uses a Queue<Order> for “orders waiting for payment confirmation,” and a Stack<Uri> for back-navigation in the admin UI.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
