Solution: Basic Calculator II
Understand how to implement a basic calculator that evaluates expressions containing non-negative integers and operators +, -, *, and /. Learn to use a stack to manage operator precedence, handle integer division truncating toward zero, and process expressions efficiently in one pass without recursion or built-in evaluation functions.

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
