Check Pending Orders

You are managing a queue of customer orders at a restaurant. Each order has a unique order ID and a preparation time in minutes. Customers can check the status of their orders either by their order ID or by viewing the next order to be processed in the queue. Implement a function to manage and simulate this order queue. Input: The first line contains an integer Q, the number of operations. Each of the next Q lines will contain one of the following: - 'ADD orderID preparationTime' to add an order (1 <= preparationTime <= 60) - 'CHECK NEXT' to check the next order ready to be processed. - 'CHECK orderID' to check the specific order. Output: For each 'CHECK' operation, print the order status: - For 'CHECK NEXT', print 'Next Order: {orderID}' or 'No Pending Orders' if the queue is empty. - For 'CHECK orderID', print 'Order {orderID} is being prepared in {remainingTime} minutes' or 'Order {orderID} not found' if the order does not exist. Example: Input: 5 ADD 123 10 ADD 456 15 CHECK NEXT CHECK 123 CHECK 999 Output: Next Order: 123 Order 123 is being prepared in 10 minutes Order 999 not found
