while(!data1.empty()){intnum=data1.top();data2.push(num);data1.pop();}intnum_=data2.top();data2.pop();returnnum_; 最后,push(int x) 函数,将一个元素放入队列的尾部。 我们知道 data1 的栈顶使当作队列的尾部,而在之前的 pop() 和 peek() 中,数据都保存在 data2 中的,因此我们先将...
A stack is a linear data structure thatfollows the Last in, First out principle(i.e. the last added elements are removed first). This abstract data type can be implemented in C in multiple ways. One such way is by using an array. Does C have a stack? No. The C11standard does ...
In this tutorial, we will learn about theworking of a Stack and Finding it's Maximum elementin the C++ programming language. To understand the basic functionality of the Stack, we will recommend you to visit theStack Data Structure, where we have explained this concept in detail from scratch....
This article has cleared most of the doubts about the stack inC++( using STL) and the functions that are used on the stack as well. Don’t know if STL is a good thing to learn. Simple Answer - Yes! As you start solving advanced data structure problems you will end up using container...
Similarly, in a queue data structure, elements are enqueued (added) at the rear and dequeued (removed) from the front. This ensures that elements are processed in the order they are added. C++ provides a powerful implementation of queues through the STL, offering a convenient way to work ...

A stack is arestricted data structure, because only a small number of operations are performed on it. The nature of the pop and push operations also means that stack elements have a natural order. Elements are removed from the stack in the reverse order to the order of their addition: ther...
