$\}$Given the following CFG and the parsing table, write a program to trace input strings

over the alphabet and ending with $$.$

Given the CFG and the Predictive Parsing table below:

poinls$]$ Write a program to trace an input string given by the user, Save it as

Prog$1$ and upload it in canvas $($either the zip file or $($GitHub link$).$ Test your

programwith the following $3$ input strings:

$(1)(a+a)**a$$

$(2)a^{**}(\frac{a}{a})S$

$(3)a(a+a)$$

$[20$ points$]$ Show the content of the stack implementation$/$stack flow after cach match.

$[20$ points$]$ Report file $-$ Your report file should contain explanation of your code, in$-$built

functions used, important checkpoints $[$if it is present$],$ explanation should be short and

crisp, output screenshot of your code and should not exceed more than $2$ pages.

Following is the grammar, and parsing table.
