Translate the automaton below into a regular expression using the algorithm described above. Note that the automaton already has a single initial and a single final state. Please draw the automaton after each step. Here a step consists of: • Removing all double arrows in the automaton. • Removing one state. • Again, remove all double arrows. It is important to follow the algorithm closely. The regular expressions have the following syntax: + for union, for concatenation and for Kleene star aor L for A, the language containing only the empty word 0 (zero) for Ø, the empty language can often be left out Example expression: abc*d(a +L + Obc)*c is short for a · b· c* ·d · (a + A + Ø • b· c)* · c. a 1 a 3 a b a

Take an Infix expression from the user and convert into postfix. 1. Should be self-organizing program e.g. If the user enters two operators back to back by mistake. The program should automatically delete one of the 2 operators. 2. If the user doesn't enter a multiplication sign before a bracket, the program should automatically insert a multiplication sign there.
A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are: The year must be divisible by 4 If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines whether that year is a leap year. Ex: If the input is 1712, the output is: 1712 is a leap year. Ex: If the input is 1913, the output is: 1913 is not a leap year. 1 2 3 4 5 6 7 8 9 10 11 Put("{} is a leap year.".format(i_year)) print("{} is not a leap year.".format(i_year)) inputYear = Get next input What would be the code?
Create a function that finds the maximum range of a triangle's third edge, where the side lengths are all integers. Note that, (side1 + side2) - 1 = maximum range of third edge Example: next_edge (8, 10) → 17 (Write in python)
A robot is initially located at position (0, 0) in a grid [−5, 5] × [−5, 5]. The robot can move randomly in any of the directions: up, down, left, right. The robot can only move one step at a time. For each move, print the direction of the move and the current position of the robot. If the robot makes a circle, which means it moves back to the original place, print “Back to the origin!” to the console and stop the program. If it reaches the boundary of the grid, print “Hit the boundary!” to the console and stop the program. A successful run of your code may look like: Down (0,-1) Down (0,-2) Up (0,-1) Left (-1,-1) Left (-2,-1) Up (-2,0) Left (-3,0) Left (-4,0) Left (-5,0) Hit the boundary! or Left (-1,0) Down (-1,-1) Right (0,-1) Up (0,0) Back to the origin! Instructions: This program is to give you practice using the control flow, the random number generator, and output formatting. You may not use stdafx.h. Include header comments.

Write a regular expression for the set of strings over the alphabet {a, b} that have at least one a and at least one b. For example, aaaba and bbaba are strings in the set, but aaaa and bbb are not. Provide a brief explanation of how your expression works.
Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. anglers have recently gotten back from a fishing excursion. The I-th angler has gotten a fish of weight man-made intelligence. Anglers will flaunt the fish they got to one another. To do as such, they initially pick a request where they show their fish (every angler shows his fish precisely once, in this way, officially, the request for showing fish is a stage of integers from 1 to n). Then, at that point, they show the fish they discovered by the picked request. At the point when an angler shows his fish, he may either become glad, become dismal, or stay content. Assume an angler shows a fish of weight x, and the most extreme load of a formerly shown fish is y (y=0 if that angler is quick to show his fish). Then, at that point: in the event that x≥2y, the angler becomes cheerful; in the event that 2x≤y, the angler becomes miserable; in the event that none of these two…
A fish-finder is a device used by anglers to find fish in a lake. If the fish-finder finds a fish, it will sound an alarm. It uses depth readings to determine whether to sound an alarm. For our purposes, the fish-finder will decide that a fish is swimming past if:there are four consecutive depth readings which form a strictly increasing sequence (such as 3 4 7 9) (which we will call "Fish Rising"), orthere are four consecutive depth readings which form a strictly decreasing sequence (such as 9 6 5 2) (which we will call "Fish Diving"), orthere are four consecutive depth readings which are identical (which we will call "Constant Depth").All other readings will be considered random noise or debris, which we will call "No Fish."Create a Python program called "fishfinder_firstname_lastname" that takes 1 input of string of 4 numbers separated with comma. Your program must display "Fish Rising", "Fish Diving.", "Fish At Constant Depth" or "No Fish".Example:30,10,20,20 Must display No…
The greatest common divisor of two positive integers, A and B, is the largest number that can be evenly divided into both of them. Euclid's algorithm can be used to find the greatest common divisor (GCD) of two positive integers. You can use this algorithm in the following manner: 1. Compute the remainder of dividing the larger number by the smaller number. 2. Replace the larger number with the smaller number and the smaller number with the remainder. 3. Repeat this process until the smaller number is zero. The larger number at this point is the GCD of A and B. Write a program that lets the user enter two integers and then prints each step in the process of using the Euclidean algorithm to find their GCD. An example of the program input and output is shown below: Enter the smaller number: 5 Enter the larger number: 15 The greatest common divisor is 5
Your objective is to write the solution to the 9 × 9 sudoku puzzle below. You must write in the digits 1 through 9 in each row such that no digit is repeated vertically, horizontally and in each box. In your solution, write each row on itsown line; and for each row, write each digit enclosed in square braces. For instance, if the row is (1, 2, 3, 4, 5, 6, 7, 8, 9), then you would type [1][2][3][4][5][6][7][8][9] for that row.
Develop a solution that will calculate the average temperature, given a set of temperatures. The number of temperatures may differ from time to time. (Use a trip values to stop the processing of the loop.) Test the solution with the following 10 temperatures. 78 90 85 80 87 83 75 90 86 70
A right triangle can have sides that are all integers. The set of three integer values for the sides of a right triangle is called a Pythagorean triple. These three sides must satisfy the relationship that the sum of the squares of two of the sides is equal to the square of the hypotenuse. Write a program to find all Pythagorean triples for side1, side2, and the hypotenuse all no larger than 30. Use a triple-nested for loop that simply tries all possibilities.

Both while loops and do-while loops are executed as long as a stated boolean condition is true and both while loops and do while loops terminate if the boolean condition is false. What is the only (major, key) difference between the two types of loops. 1. while loops are faster 2. A do-while loop can be rewritten as a for loop, but we cannot rewrite a while loop as a for loop. 3. A do while loop will always execute the loop statements once, but it is possible that a while loop skip all of its loop statements.
