This loop holds a counter whose values control the number of times the
loop iterates. The iteration stops upon attaining the number of times of
loop being specified.

Loop is used to repeat a sequence of actions or statements many times. Simplydescribe the differences between for-loop and while-loop.
A for construct is an iterative loop that processes a list of items. As a consequence, it continues to process items as long as there are things to process. Is this a true or false statement?

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.arrow_forward
- A for construct is a kind of loop that operates on items included in a list. Because of this, it continues to operate for as long as there are objects to be processed in the system. Is this statement correct or does it include an error?arrow_forwardCelebrity problem A celebrity among a group of n people is a person who knows nobody but is known by everybody else. The task is to identify a celebrity by only asking questions to people of the form: ”Do you know him/her?” Solution Select two people from the group given, say, A and B, and ask A whether A knows B. If A knows B, remove A from the remaining people who can be a celebrity; if A doesn’t know B, remove B from this group. Solve the problem recursively for the remaining group of people who can be a celebrity Which design strategy does the following solution use?

Hint: if you want to print a new line, you can print an empty string, e.g., print(""). For this task, we will draw a simple text-based circle. Recall that a circle is described as follows: x² + y² = r² Any x, y value, such that x² + y² ≤ r², will be a point inside or on the circle. With this simple information, we can draw a circle. Your task should work as follows: (1) Ask the user to input a radius from [1 to 10]. -> You can assume the input is an integer -> If the value is not between 1 and 10, keep asking for input [see example below] (2) loop y from 10 to 10 loop x from 10 to 10 if the current x,y is inside or on the circle (see equation above), then print a '*', otherwise print a '.' hint: consider using print (..., end="") Examples of Task 2 (user input in red) Task 2: Draw circle ---- Input size between 1-10: 11 Input size between 1-10: 0 Input…arrow_forward
- (For review) a. What’s the difference between a pretest and posttest loop? b. If the condition being tested in a pretest loop is false, how many times are statements in the loop executed? c. If the condition being tested in a posttest loop is false, how many times are statements in the loop executed?arrow_forwardThe term "for construct" refers to a type of loop that can iterate over multiple items. So long as there are objects to process, it will continue to operate. Is this a true or false statement?arrow_forwardOverview In this assignment, you will gain more practice with designing a program. Specifically, you will create pseudocode for a higher/lower game. This will give you practice designing a more complex program and allow you to see more of the benefits that designing before coding can offer. The higher/lower game will combine different programming constructs that you have been learning about, such as input and output, decision branching, and a loop. Higher/Lower Game DescriptionYour friend Maria has come to you and said that she has been playing the higher/lower game with her three-year-old daughter Bella. Maria tells Bella that she is thinking of a number between 1 and 10, and then Bella tries to guess the number. When Bella guesses a number, Maria tells her whether the number she is thinking of is higher or lower or if Bella guessed it. The game continues until Bella guesses the right number. As much as Maria likes playing the game with Bella, Bella is very excited to play the game…arrow_forward
- Purpose: One of the most commonly made decisions is based on comparing the means of multiple conditions. Significance tests for comparing means are critical in the decision making process. In this assignment, you will practice how to use t tests and ANOVA tests to compare the means of multiple conditions under one independent variable in different experiment design (between-group and within-group) Tasks: Please write an R script that performs the following operations in the order listed. At the beginning of each task, write a comment marking the task number. Name the file as: lab6-<your last name>.R ANOVA tests 8. Import the 'iris.csv' dataset. Browse and understand the data in each column 9. Compute descriptive statistics and create boxplot for sepal length and species. 10. Select the appropriate test to determine whether there is significant difference in sepal length between the three species. Follow the steps of ANOVA analysis. Make sure you check whether the assumptions are…arrow_forwardAuto-graded programming assignments may use a Unit test to test small parts of a program. Unlike a Compare output test, which evaluates your program's output for specific input values, a Unit test evaluates individual methods to determines if each method: is named correctly and has the correct parameters and return type • calculates and returns the correct value (or prints the correct output) This example lab uses multiple unit tests to test the kilo ToPounds() function. Complete a program that takes a weight in kilograms as input, converts the weight to pounds, and then outputs the weight in pounds. 1 kilogram = 2.204 pounds (lbs). Ex: If the input is: 10 the output is: 22.040000000000003 lbs Note: Your program must define the method public static double kiloToPounds (double kilos) The program below has an error in the kilo ToPounds() method. 1.
