Dear Students!

Graded Discussion board will be launched on Tuesday, 12th August, 2014 and it will remain open for two days.

Graded Discussion Topic:

There are two types of parsing techniques, Top-down and Bottom-up. Considering an ambiguous grammar, which parsing technique is more appropriate to use? Discuss it with proper reasoning.

A concise, coherent and to the point comment is preferred over lengthy comment having irrelevant details. Your comment must not be more than 5-7 lines. Comments, posted on regular Lesson's MDB or sent through email will NOT be considered in any case. Any request about such an acceptance will not be catered.


Best of Luck!

is consumed, the parser encodes possibilities in an internal state. The bottom- up parser

starts in a state valid for legal first tokens. Bottom-up parsers handle a large class of

Bottom-up parsing is best for ambiguous grammar

I also agree with Bottom-up parsing

1. error detection is fast than top down parser

2.widely used for computer languages

3.cover the large class of grammars

4.handles the Left-Recursion

5.produce the correct parse without guessing
