Construct an NFA for the regular expression ((a+b)*c)* such that the structure of the NFA directly corresponds to the structure of that expression. Submit Below, explain how the parts of your NFA correspond to the components of that regular expression.

Question on algebra of regular expressions. Use regular algebra to prove that (a+ab)*a=a(a+ba)*.
Q2: Describe the following regular expressions using set builder notation then show the equivalent NFA( show the stages of the NFA creation). 1) ?∗101?∗ where ? = {0,1} 2) ?∗(??+)∗ 3) 01* ∪ 10*
1. Write regular expressions to capture the following regular languages: (a) The set of binary strings which have a 1 in every even position. (Note: odd positions may be either 0 or 1.) (b) The set of binary strings that do not contain 011 as a substring. (c) Comments in Pascal. These are delimited by (* and *) or by { and }, and can contain anything in between; they are NOT allowed to nest, however. 2. Write a DFA...
