Description

Experience Level: Intermediate
General information for the business: Compiler software building
Kind of development: New program from scratch
Num. of modules: 5
Description of every module: Implement utilities for LL(1) parsing:

a) A function LeftFactor which left-factors a given CFG.

b) A function LeftRecElim which eliminates left recursion from a given CFG. (Assume the
CFG has no "-rules and no cycles.)

c) A function First which computes the First set for all terminals and variables of a given
CFG.

d) A function Follow which computes the Follow set for all variables of a given CFG.

e) A function Table which constructs the LL(1) parsing table for a given CFG.
Description of requirements/functionality: a) A function LeftFactor which left-factors a given CFG.

b) A function LeftRecElim which eliminates left recursion from a given CFG. (Assume the
CFG has no "-rules and no cycles.)

c) A function First which computes the First set for all terminals and variables of a given
CFG.

d) A function Follow which computes the Follow set for all variables of a given CFG.

e) A function Table which constructs the LL(1) parsing table for a given CFG.
Specific technologies required: c#
OS requirements: Windows
