LABView Draw by hand the diagram for a program that displays a count that increments 4 times per seconduntil the user pushes a stop button. Turn on a boolean light when the count is even. Thecount starts at 0 and goes until the user pushes the stop button.

Part 6: Boolean Logic Expressions Boolean expressions are types of logical operations that we can perform on true and false values. Note that the word Boolean is always capitalized because it was named after its inventor, George Boole. Boolean algebra is a very important topic in computer science, and if you haven't learned it before you definitely will in the future. However, for our purposes we are only interested in how we can use them to manipulate binary numbers. The way we use them on binary numbers is by treating 1 as true and 0 as false. From this point on I will be using 0 and 1 instead of false and true. There are many types of Boolean expressions, but the three most important ones are AND, OR, and NOT. AND takes 2 operands and will output 1 if they are both 1, or 0 otherwise OR takes 2 operands and will output 1 if either one is 1, or 0 if neither is 1 NOT takes 1 operand and reverses it: 1 becomes 0, and 0 becomes 1 We can represent this behavior using something called a…

Algorithm writing Instructions: Algorithms are a generic way of describing a solution to a computational problem without use of any specific programming language syntax. It cannot be executed on a real computer, but it can model and resemble real programming code. Natural language is used whenever details are unimportant or distracting. Your algorithm: Must be unambiguous (exact)..are the steps numbered? .do we always know where to go next or are we left hanging? Must be correct (solves the problem)...are the 'requirements' being met? Must come to an end (terminate)...how do we know when to end this? Must be general (for all cases).. .can we input any data & still solve the problem? Must be at the right level of detail... . will a computer (in general) understand what we are asking it to do? Requirements --> You have a store that sells lemons and oranges. Oranges are $.30 each and lemons are $.15 each. Your solution to this problem should get from the user the numbers of oranges and…

In computer programming, more information is always better than less; yet, you shouldn't make a decision based only on performance.

The properties of an algorithm should be mentioned.

Python Algorithms Part 1 – Binary SearchLet's play a little game to give you an idea of how different algorithms for the same problem can have wildly different efficiencies. If I choose an integer from 1 to 16 and ask you to guess what the number is, you can keep guessing numbers until you hit on it. When you guess wrong, I tell you whether you are too high or too low. Once you've guessed the number, think about the technique you used to decide each of your next guesses.If you guessed 1, then 2, then 3, then 4, and so on, until you guessed the right number, you used an approach called “linear search,” meaning you guessed the numbers serially and sequentially, as if they were lined up in a row. This is definitely one way to find the mystery number, but it could require as many as 16 guesses. However, you could get lucky, if the number was 1, you’d only need 1 guess. Using a linear search process, on average, you'd need 8 guesses.There is an approach that is more efficient than just…

Computer Science Using computers and other automated tools to grade true-false and multiple-choice tests is widespread, but grading essays has been reserved for instructors. Until now. Software developed by a nonprofit enterprise founded by Harvard and MIT recently released software that can grade student essays and short written answers. Students answer online instead of in a blue book and immediately receive their grade after clicking a Send button. The software uses artificial intelligence (it initially “learns” how to grade an instructor’s test by reviewing 100 essay exams that the instructor scored) and is designed to free up professors for other tasks, as well as give students the opportunity to immediately revise their graded essays for an improved grade. But does the system work? Are the automated grades similar to what a human grader would award? Skeptics (including the National Council of Teachers of English) say no. Objections include a lack of tests to support the validity…

When discussing an algorithm, it's important to highlight its qualities.

Question-1 Friend's Party Circle: There are a few friends living in the same area. They have a party every weekend and the place of party change each week. It is always a lifficult task to select a place which is nearest for everyone. They advantage of Computer Science to solve this problem. all decided to take Names of friends are Ahmed, Rehman, Careem, Basit, Dawood, Ghani, and Farid. Ahmed lives at 5 minutes' walk from rehman and at 10 minutes' walk from Careem. Careem lives at 3 minutes' walk from Dawood. Rehman lives at 4 minutes' walk from Basit and 2 minutes' walk from Dawood. Dawood lives at two minutes' walk from Farid. Ghani lives at 2 minutes' walk from Basit. a. If we represent a graph G = V (V, E) in which set of vertices are home of each Friend and an edge represents a path between two homes. Provide the adjacency matrix of directed graph of the graph G. b. In above directed graph G. You are required to devise an algorithm to find all possible paths.

It is important to call attention to certain characteristics of an algorithm.

When explaining an algorithm, it is critical to emphasise its strengths.

A well-considered algorithm will have no room for interpretation.

ID: A Name: ID: A 6. There are 32 students standing in a classroom. Two different algorithms are given for finding the average height of the students. Algorithm A Step 1: All students stand. gniwolldi odT gaihnel vd Step 2: A randomly selected student writes his or her height on a card and is seated. Step 3: A randomly selected standing student adds his or her height to the value on the card, records the new value on the card, and is seated. The previous value on the card is erased. Step 4: Repeat step 3 until no students remain standing. Step 5: The sum on the card is divided by 32. The result is given to the teacher. Algorithm B Step 1: All students stand. Step 2: Each student is given a card. Each student writes his or her height on the card. Step 3: Standing students form random pairs at the same time. Each pair adds the numbers written on their cards and writes the result on one student's card; the other student is seated. The previous value on the card is erased. Step 4: Repeat…

An algorithm that has been carefully thought out should be free of ambiguity."

Skydiving Bibi is a skydiving instructor. Before carrying out skydiving activities, Bibi will always ask the name, height, and age of the participants. Bibi's participants is always 2 people. To make it easier to remember their identities, Bibi gave them a paper to write down their identity. But because they are very enthusiastic in doing skydiving, they write their identity in a single line only (for both of the participants), so it wasn't quite neat and it made difficult for Bibi to see it, and resulted in the skydiving process being disturbed. As one of the organizer committee, you do not want this activity to be disturbed and plan to provide a program that provides their identity neatly to Bibi. Format Input Input consists of 1 line. It contains the identity of 2 people in a row Ni, Ti, Ui - the name, height, and age of the i-th participant. Format Output The output consists of 6 lines. The first line, "Name 1: N1". The second line, "Height 1: T1". The third line, "Age: U1". For…

Exercise B: Some initial values may make the PageRank algorithm converge faster, you can use a program to try different initial values. You can use a smaller floating number precision (fewer decimal places) to converge faster. Or you can assume if the PageRank values change in less than a certain percentage (e.g., 5%), they are converged.
