class MyQueue { private Stack input; private Stack output; public MyQueue() { this.input = new Stack(); this.output = new Stack(); } public void push(int x) { input.push(x); } public int pop() { if (!output.isEmpty()) return output.pop(); while(!input.isEmpty()){ output.push(input.pop()); } return output.pop(); } public int peek() { if (output.isEmpty()) while (!input.isEmpty()) output.push(input.pop()); return output.peek(); } public boolean empty() { return (input.isEmpty() && output.isEmpty()); } } // thank me later!
