请原谅我直接,这一题。。。我这么傻心里都嘀咕,怎么出得那么傻~没有灵魂得题目。
class MyCircularQueue { List<Integer> queue = new ArrayList<>(); Integer capacity = 100000; public MyCircularQueue(int k) { capacity = k; } public boolean enQueue(int value) { if (queue.size() < capacity) { queue.add(value); return true; } return false; } public boolean deQueue() { if(queue.size() == 0) { return false; } queue.remove(0); return true; } public int Front() { if(queue.size() == 0) { return -1; } return queue.get(0); } public int Rear() { if(queue.size() == 0) { return -1; } return queue.get(queue.size() -1); } public boolean isEmpty() { return (queue.size() == 0); } public boolean isFull() { return (queue.size() == capacity); } } /** * Your MyCircularQueue object will be instantiated and called as such: * MyCircularQueue obj = new MyCircularQueue(k); * boolean param_1 = obj.enQueue(value); * boolean param_2 = obj.deQueue(); * int param_3 = obj.Front(); * int param_4 = obj.Rear(); * boolean param_5 = obj.isEmpty(); * boolean param_6 = obj.isFull(); */View Code
