Given the grammar defined by the following Extended BNF set of production rules:

A sample program in this language:

Note: (1) The tokens in bold letters are reserved words. (2) Other symbols as they appear in the production rules.

* Write a recursive descent parser for the above grammar.

* Your program will be tested with random programs.

* Your program will be graded according to the correctness, style, and documentation.

Please I need the program written in C (and Python if possible)
