Tutorial Week 5 Task 1. Consider the following grammar, which is ambiguous and left-recursive. E ::= E+E | E*E | -E | E/E | 0 | 1 | 2 | … Convert the grammar into a form that is free from left-recursion, but has the same language. It’s fine if your translation makes the language

How to select Scheme? Scheme is 25% of CSc 600. The goal of studying Scheme is to understand the spirit of functional programming. Another goal is to understand a minimalistic approach to programming, and what can be derived from the simple concept of a list with operator and operands, dynamic typing, tail recursion, passing of
