8, Calculate the value of a mathematical expression (Binary Tree)
[Problem description]
Given a mathematical expression, calculate its value by constructing binary
tree. The mathematical expression begins and ends with #. Output the
postorder traversal sequence of the constructed binary tree at the same time.
Because the binary tree corresponding to a mathematical expression is not
unique, the preorder traversal sequence is also not unique. Any feasible
preorder traversal sequence is ok.
[Basic requirements and Example]
What you need to show in the terminal (the back part is outputted by you and
the blue part is inputted by the user, i.e., teacher):
Please input the mathematical expression:
#1+2*(4-3)-8/2#
The value is:
-1
The postorder traversal sequence is:
-+1*2-43/82

Process or set of rules that allow for the solving of specific, well-defined computational problems through a specific series of commands. This topic is fundamental in computer science, especially with regard to artificial intelligence, databases, graphics, networking, operating systems, and security.
