Rust Programming Master Class from Beginner to Expert - Implementing Postfix Evaluation

This tutorial covers the evaluation of postfix expressions in Rust. It begins with a review of postfix rules, followed by defining a function for evaluation. The tutorial explains variable declaration, using a match statement to implement rules, and defining an operation function. It concludes with final steps and a brief discussion on code optimization.

What is the significance of the default case in the match statement for operations?

How is the final result obtained from the stack after evaluating the postfix expression?

What is the role of the print statement in the main function regarding the postfix evaluation?

Discuss any potential optimizations that could be made to the postfix evaluation code.
