232. Implement Queue using Stacks 仅供自己学习 思路: 这里只用两个栈来模拟队列,因为栈是先进后出,队列是先进先出,所以一个栈instack用来存进来的元素,另一个栈outstack存instack弹出的元素,且若instack要将元素加入进outstack中,只有当outstack空了才能重新加入新进instack得元素,否则顺序将错误。这样队列就能...

Depending on your language, stack may not be supported natively. You may simulate a stack by using a list or deque (double-ended queue), as long as you use only standard operations of a stack. You may assume that all operations are valid (for example, no pop or peek operations will be...

As far as i can think this cannot be done for a single threaded application(correct me if i am wrong). I don't know if it can be done using select as the demultiplexer, but even if select could be used, the event loop would require one thread ? Isn't it ?
