1. Recall that a left-linear grammar is a grammar in which all non-terminals (i.e. variables) are on the left end of the right side of production rules, while a right-linear grammar is a grammar in which all non-terminals (i.e. variables) are on the right end of the right side of production rules.

a) Find a left-linear grammar that generates L = {an bm : n 3, m 2}

b) Find a right-linear grammar that generates L = {an bm : n 3, m 2}

Need help for above problem. Thank you.
