Problem 2. The longest common substring problem is to find the longest string that is a substring of two strings. The longest common substring of the strings "ABABC", and "ABCBA" is string "ABC" of length 3. A substrings of strings is a series of consecutive letters of s. For example, "ABA” is a substring of “ABABC", but "ABAC" is not a substring of "ABABC". Design an algorithm such that...
2. Prove that {a"6"c" |m,n0}is not a regular language. Answer: 3. Let L = { M M is a Turing machine and L(M) is empty), where L(M) is the language accepted by M. Prove L is undecidable by finding a reduction from Aty to it, where Arm {<M.w>M is a Turing machine and M accepts Answer: 4. a) Define the concept of NP-completeness b) If A is NP-complete, and A has a polynomial time algorithm, then a polynomial time algorithm...

Problem 4. Here's a problem that occurs in automatic program analysis. For a set of variables x1, ..., Xn, you are given some equality constraints, of the form "x, = x," and some disequality constraints, of the form “x, #x": Is it possible to satisfy all of them? For instance, the constraints x, = XX, = x3,x; = x, *, * x. cannot be satisfied. Give a polynomial time...

Prove that the language is regular or not. {a^nb^m | n >= m and m <= 481}
Exercise 4.1.1: Prove that the following are not regular languages a) (0"1n|n 2 1). This language, consisting of a string of 0's followed by an cqual-length string of 1's, is the language Loi we considered informally at the beginning of the scction. Here, you should apply the pumping lemma in the proof. b) The set of strings of balanced parentheses. These are the strings of char- acters "(" and " that can appear in a well-formed arithmetic expression *c) O"IO"...
6.[15 points] Recall the pumping lemma for regular languages: Theorem: For every regular language L, there exists a pumping length p such that, if s€Lwith s 2 p, then we can write s xyz with (i) xy'z E L for each i 2 0, (ii) ly > 0, and (iii) kyl Sp. Prove that A ={a3"b"c?" | n 2 0 } is not a regular language. S=
