Write a regular expression for the language.
(2)
Define a finite state machine (FSM) that recognizes words in the language (input alphabet, states, start state, state transition table, and accept states). Include a state digraph for the FSM.
A: For alphabet {p,q,r}, all strings that contain the substring rqr or end with pp.
given alphabet{p,q,r}
a regular expression for DFA
now taking qf
putting the value of q4
qf=q1p+q3rp+q3rq+q4rr
now putting the value of q1
qf=qsp+q2p+q3p+q3rp+q3rq+q4rr
now putting the value of q3
qf= q2p+q2qp+q2qrp+q2qrq+q4qrr
qf= q2(p+qp+qrp+qrq+qrr)
regular expression for rqr will become

Write Java code to implement a FSM machine that recognizes the language for the alphabet {a,b,c} consisting of all strings that contain two consecutive c's and end with b. Your FSM program should include the following three static methods (Java) or functions (C): a. int nextState(int state, char symbol) A state-transition function that returns the next state based on the current state and an input symbol. This function should also return -1 when an invalid input character is detected. State...
Design a finite state machine that recognizes the input string "k", "klm", and "mkl" by outputing a "1" (otherwise output "0" for the input). the input alphabet is {k, l, m}. the output alphabet is {0,1} i) Draw the FSM ii) Create the state transition table iii) what is the sequence of states for kkkllmklmkmmkm
Construct a regular expression that recognizes the following language of strings over the alphabet {0 1}: The language consisting of the set of all bit strings that start with 00 or end with 101 (or both). Syntax The union is expressed as R|R, star as R*, plus as R+, concatenation as RR. Epsilon is not supported but you can write R? for the regex (R|epsilon).
Table Q4.1 shows the state transition table for a finite state machine (FSM) with one input x, one output z and eight states. (a) Copy the table of Table Q4.2 into your examination book and determine the states and outputs for the input listed, assuming a start current state of ‘1’. Determine what function the FSM is performing. (b) Using the implication chart method, determine the minimal number of states. Show clearly your analysis. (c) Draw the reduced state transition...
In either Java or Python 3, write a program that simulates a deterministic FSM. It will read from two input files. The first is a file describing an FSM The first line contains the alphabet as a series of characters separated by a single space - The second line contains the number of states as an integer k 2 1; states will be numbered 0,1,..., k -1. The start state is always state O The third line contains a series...

Construct the state digraph (including accept states) of a Moore machine that accepts all strings that start with b and end with baa. The input alphabet is A = {a, b].
Finite state machines & Regular Expressions Please select the best option 1. For the following questions Let r, s, t be regular expressions for the same alphabet "á" (left column). Get the property on the right side that produces equality for each regular expression. 2. From the diagram of the solution M = (Σ, Q, s,, F) is respectively: e would be NONE. 3. The following graph corresponds to a diagram of: A. Transition machine and states b. Transition...

Question 1 - Regular Expressions Find regular expressions that define the following languages: 1. All even-length strings over the alphabet {a,b}. 2. All strings over the alphabet {a,b} with odd numbers of a's. 3. All strings over the alphabet {a,b} with even numbers of b’s. 4. All strings over the alphabet {a,b} that start and end with different symbols. 5. All strings over the alphabet {a, b} that do not contain the substring aab and end with bb.
