Method analysis:

Empty(): judge whether the stack is empty. If it is empty, return true; otherwise, return false

Peek(): takes out the top element of the stack, but does not remove the element from the stack

Pop (): take out the top element of the stack and remove it from the stack

Push (eitem): element stacking

Search (objecto): find the element position in the stack. The position is calculated from the top of the stack to the bottom. The top of the stack is 1,

Count down to the position of the searched element. If the searched element does not exist in the stack, it returns - 1.

The above methods are the methods that stack inherits from the vector extension. Because stack inherits from vector, which is the non private method in vector

It is also a method of the stack class.
