Example 1:

\n\n
\nInput\n["MyCircularDeque", "insertLast", "insertLast", "insertFront", "insertFront", "getRear", "isFull", "deleteLast", "insertFront", "getFront"]\n[[3], [1], [2], [3], [4], [], [], [], [4], []]\nOutput\n[null, true, true, true, false, 2, true, true, true, 4]\n\nExplanation\nMyCircularDeque myCircularDeque = new MyCircularDeque(3);\nmyCircularDeque.insertLast(1);  // return True\nmyCircularDeque.insertLast(2);  // return True\nmyCircularDeque.insertFront(3); // return True\nmyCircularDeque.insertFront(4); // return False, the queue is full.\nmyCircularDeque.getRear();      // return 2\nmyCircularDeque.isFull();       // return True\nmyCircularDeque.deleteLast();   // return True\nmyCircularDeque.insertFront(4); // return True\nmyCircularDeque.getFront();     // return 4\n
