Queue Implementation using Two Stacks in C++: Here, we are going to implement a C++ program to implement Queue using two Stacks.
(Assume 64-bit x86-64 architecture and Intel 3rd/4th generation CPU) Here is a lock-free implementation for a stack from Concurrency in Action book, page 202: It says below the code: On those platform...Glide Does not use Cached Image Hi I am using Glide to load image and after fol...

In their implementation in the C++ Standard Template Library,queues take two template parameters: template<classT,classContainer = deque<T> >classqueue; push(x)将元素压入队列 pop()弹出首部元素 front()获取首部元素 back()获取尾部元素 empty()队列为空则返回1,不为空返回0 size()返回队列中元素的个...
