This is because the stack is a LIFO data structure, which means that theelement inserted last is retrieved first. Note: Unlike vectors or other containers, we cannot use a rangedforloop to iterate through a stack. This is because the STL stack is anSTL Container Adapter, which provides rest...
In this tutorial, we will learn about theworking of a Stack and its implementationin 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. For a bett...
Stack is an abstract data type, a linear data structure that holds a collection of elements that are added or removed in a Last In First Out (LIFO) manner. This means the element added at the top will be removed first, just like we have a pile of plates one on top of the other an...

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...
