Compute CLR-1 and LALR-1 Table of following grammar,
Compute CLR-1 and LALR-1 Table of following grammar, Analyze the table and find,
if there are any conflicts?? If YES, what type of conflicts are they?? Also parse
following input along semantic rules by showing stack state while parsing.
a id bi id * +
[CLO-4, PLO-36] (10+4)
S→SE+|Ef|F { print top of stack 2 times}
E→EE*|F {if top of stack is E , print Good, else print Bad }
F→aF|bi|id {print how many elements are there in stack}
