Homework #4: LL(1) and LR Parsing Table Construction - Due Dec 6, 2011

This homework assignment focuses on constructing parsing tables for specified grammars. In Chapter 5, part 5.2, you are required to create the LL(1) parse table for the grammar defined by the productions: Expr → -Expr | (Expr) | Var ExprTail, where ExprTail and Var are defined similarly. Subsequently, in Chapter 6, you'll build a CFSM for a provided grammar and demonstrate the LR parse table derived from it. Additionally, complete the SLR(1) construction for a grammar shown in Fig. 6.26, and submit a handwritten version in class by December 6, 2011.
