Design your implementation of the circular double-ended queue (deque). Your implementation should support following operations: MyCircularDeque(k): Constructor, set the size of the deque to be k. insertFront(): Adds an item at the front of Deque. Return true if the operation is successful. insertLast(): Adds an item at the rear of Deque. Return true if the operation is successful. deleteFront(): Deletes an item from the front of Deque. Return true if the operation is successful. deleteLast(): Deletes an item from the rear of Deque. Return true if the operation is successful. getFront(): Gets the front item from the Deque. If the deque is empty, return -1. getRear(): Gets the last item from Deque. If the deque is empty, return -1. isEmpty(): Checks whether Deque is empty or not. isFull(): Checks whether Deque is full or not. Example: MyCircularDeque circularDeque = new MycircularDeque(3); // set the size to be 3 circularDeque.insertLast(1); // return true circularDeque.insertLast(2); // return true circularDeque.insertFront(3); // return true circularDeque.insertFront(4); // return false, the queue is full circularDeque.getRear(); // return 2 circularDeque.isFull(); // return true circularDeque.deleteLast(); // return true circularDeque.insertFront(4); // return true circularDeque.getFront(); // return 4 Note: All values will be in the range of [0, 1000]. The number of operations will be in the range of [1, 1000]. Please do not use the built-in Deque library.
