Expression Trees:
Binary Trees representing arithmetical or syntax expressions. A few examples:
- Reverse Polish notation
- Postfix expressions
- Order of operations () nested expressions
Programming question: Write a program that can parse complex expression syntax like,
"(a+b)/(c+(d*e))"
Shunting Yard Algorithm
