Consider the following statements:

Statement I: LALR parser is more powerful than canonical LR Parser.

Statement II: SLR parser is more powerful than LALR.

Which of the following is correct?

The power hierarchy of LR parsers is:

$SLR < LALR < Canonical\ LR$

Now check Statement I:

Statement I says that LALR parser is more powerful than canonical LR Parser.

But actually Canonical LR parser is more powerful than LALR parser.

So, Statement I is false.

Now check Statement II:

Statement II says that SLR parser is more powerful than LALR.

But actually LALR parser is more powerful than SLR parser.

So, Statement II is false.

Therefore, both Statement I and Statement II are false.
