Solution: Basic Calculator II
Understand how to implement a stack-based solution to evaluate mathematical expressions containing addition, subtraction, multiplication, and division. Learn to process operators with correct precedence without recursion or built-in evaluators, efficiently managing intermediate results and integer truncation.

Statement
Given a string s representing a mathematical expression containing non-negative integers and the operators +, -, *, and /, evaluate the expression and return its result.
Integer division must truncate toward zero. You may assume the expression is always valid, and all intermediate results fall within the
