Please I need help with this assignment

In this assignment, you will use top-down parsing rather than bottom-up parsing (as implemented using YACC). Consider Boolean expressions, with the following operations: and, or, and not (standard associativity and precedence), brackets are allowed. If below you are asked to "write ...", then you have to include the required description as a part of your documentation. If you are asked to "implement...", then you have to write a program. Part 1. Write an S-attributed syntax directed translation for Boolean expressions with the following tokens: true, false, and brackets, which can be used to evaluate these expressions. Note: carefully study examples from the textbook of S-attributed syntax directed translations for arithmetic expressions, to learn how to design them to express correct precedence and associativity rules. Then, write an L-attributed translation resulting from removing left recursion. Note: carefully study examples from the textbook showing how left-recursive S-attributed translations can be converted to L-attributed translations. Finally, implement a lexical analyzer (use Lex or write it by hand) and a recursive-descent translator based on the above translation. Examples: true and not false not false or (false and not false and true or false) are both correct, and evaluate to true, but 1 and true is invalid.
