- 6. Draw a NFA that accepts all strings over > = substring bb. {a,b} that either end in ab or contain the 7. Convert the NFA in the previous exercise to a DFA. Draw the transition diagram. 8. Draw a NFA that accepts all strings over Σ = {a,b} that have both aa and bb as substrings. 9. Convert the following NFA to a DFA. Draw the transition diagram.Given the following UML diagram: Student - studentID: String + getStudentID(): String + toString(): String Person - lastName: String - firstName: String - dateOfBirth: Date - address: Address + getName(): String + getDOB(): Date + getAddress(): Address + toString(): String Professor - employeeID: String +getEmployelD(): String +toString(): String Write an implementation for the class Professor. DO NOT include or implement any constructor for this class. There are no abstract methods/classes in this example. toString method will return any simple String that contains firstName and employeelD only; no less, no more!! Assume firstName was defined as protected in class Person. You are not allowed to add implementation for any class or methods other than what is listed in the question statement.Q3.

Bob and Alice are sitting in their favorite pub andit’s happy hour.They want to invite their common friend Johnwho likes cocktails and didn’t know about thenewly scheduled happy hour. Alice takes out her“mobile phone” and activates the “SMS”function.2. Alice enters John’s cell phone number andwrites the message about the happy hour intothe “SMS text field”. She sends the messageand waits for John’s answer.3. John, who is still at work, is alerted by a soundof his cell phone that a new “SMS” has arrived.He reads the lines from Alice and answers thathe will come immediately. He quits working andleaves the office.4. Alice receives John’s answer at her “mobilephone”.Figure 1

Berland local ICPC challenge has quite recently finished. There were m members numbered from 1 to m, who contended on a problemset of n issues numbered from 1 to n. Presently the article is going to happen. There are two issue creators, every one of them will tell the instructional exercise to precisely k back to back errands of the problemset. The creators pick the section of k continuous errands for themselves autonomously of one another. The sections can correspond, meet or not cross by any means. The I-th member is keen on paying attention to the instructional exercise of all continuous errands from li to ri. Every member consistently decides to pay attention to just the issue creator that tells the instructional exercises to the most extreme number of assignments he is keen on. Leave this greatest number alone artificial intelligence. No member can pay attention to both of the creators, regardless of…

(a) Draw a simple graph that models the walkways and attractions of the carnival given the following information: • the entrance is an attraction because of the funny clowns that perform • from the clowns you can go to the slide, food truck, or carousel • the food truck is also connected to the petting zoo, ice cream cart, and ring toss • you can get to the petting zoo from the slide as well • from the carousel you can go to the face painting station or the ice cream cart, but there is also a direct path between the ice cream cart and face painting station too • the ice cream cart and ring toss both lead to the fishing game (b) To advertise the event, (i) Can the charity claim each attraction can be visited exactly once? (e.g. does the graph have a Hamilton circuit? or a Hamilton path?) If so, give one example, as proof. (ii) For members of…. The following UML diagram is provided for a Student object: Uml instructions Student -name:string -stNumber:string -partMark:int -examMark:int +Student() +Student(name:string,partMark:int,examMark:int) +getStNumber():string +getPartMark():int +getExamMark():int +determineStNumber():string +calcModuleMark():double +toString():string 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a…
- Pleaae answer all subparts....either dislike is ready....Minimize the following DFA a. Fill out the transition table for the minimum state DFA. Label out start and final states: Start/Final? DFA states a b b. Give the transition table with renamed states, and draw the graph version of the DFA for this table.(b) KLM-GOMS stands for Keystroke-Level Model for Goals, Operators, Methods, and Selection rules. It allows designers to predict how long it will take a skilled user to execute a specific set of actions using a particular interface design. The standard set of operators are: • Keying (K): for typing a key or clicking a control - 0.2s Pointing (P): pointing with a mouse to a target on a display - 1.1s • Homing (H): home hands on keyboard or other input device - 0.4s Mentally Preparing (M): think before doing an action - 1.35s Responding (R): time a user must wait for a response Once you determine the operators, you need to apply the following rules for mental operations before calculating the time. Rule 0: Add Ms in front of all Ks and all Ps that point to commands. Rule 1: Change PMK to PK to remove fully anticipated Ms. Rule 2: Eliminate any Ms in the middle of strings that are part of a cognitive unit (a contiguous sequence of typed characters). Rule 3: Delete Ms before consecutive…
