问题描述
What is the best way to implement a Stack and a Queue in JavaScript?
I'm looking to do the shunting-yard algorithm and I'm going to need these data-structures.
解决方案
var stack = [];
stack.push(2); // stack is now [2]
stack.push(5); // stack is now [2, 5]
var i = stack.pop(); // stack is now [2]
alert(i); // displays 5
var queue = [];
queue.push(2); // queue is now [2]
queue.push(5); // queue is now [2, 5]
var i = queue.shift(); // queue is now [5]
alert(i); // displays 2
