Implement a Delivery and Collection Algorithm

Design a package delivery and collection system. Implement the following features: Users can request to have packages delivered to specific lockers. Users can request to collect packages from lockers. The system should support adding new lockers and checking locker availability. Implement a data structure that supports efficient delivery and collection operations, and provide code to satisfy these requirements. Provide at least three test cases to verify your system. Input A series of string commands, each representing an action: addLocker() - Add a new locker deliverPackage(packageId, lockerId) - Deliver package with packageId to locker lockerId pickupPackage(packageId) - Pickup a package from the locker Output Output the result of each operation on a new line. Constraints Total number of lockers will not exceed 1000. Total number of packages will not exceed 10000. Example Input addLocker() deliverPackage(1, 0) pickupPackage(1)
