Top-Down Parser Simulation on Java.

Top-Down-Parser

Given a context-free grammar on a txt file, the app will remove left recursion and apply left factoring if needed. Then based on FIRST and FOLLOW sets, it will generate a parse table which can be tested with some words examples. You can test it with the exemple.txt file that's in the folder.
