Token Tree - Parse and Evaluate an Expression Tree from Tokens

Problem You are given a list of tokens representing a mathematical expression in prefix notation. Build the expression tree and evaluate it. Tokens are either operators (+, -, *, /) or integer literals. Example: Approach Use a recursive descent parser with a pointer into the token list. Each call to parse() consumes one operator and recursively parses its two operands. Follow-ups Extend to handle unary operators (e.g., negation). How would you convert an infix expression to prefix notation first…
