Recall that Levi is a statically-scoped language. Assume a new variant of Levi, called Levi', that uses the exact same syntax as Levi but is dynamically-scoped. Provide an input file that would be valid in both Levi or Levi', but prints a different result based on which scoping system is used. Show what the output would be either under scheme.
Provide an input file that would be valid in Levi', but not in Levi.
Explain the difference between an SLR and an LR(0) parser. Provide an example grammar that is SLR-parseable but not LR(0) parseable.
