- (Factorials) The factorial function is used frequently in probability problems. The factorialof a positive integer n (written n! and pronounced “n factorial”) is equal to the product of the positive integers from 1 to n. Write a program that evaluates the factorials of the integers from 1 to 5.Print the results in tabular format. What difficulty might prevent you from calculating the factorialof 20?arrow_forward(PYTHON) A Krishnamurthy number is a number which sum of the factorial of its digits is equal to the number itself. For example: Let us consider the number 145. Factorial sum = 1! + 4! + 5! = 1 + 24 + 120 = 145. Therefore 145 is a Krishnamurthy number. Other examples include: 1, 2, 40585. Write a program that does the following: • asks the user to input an integer. • computes whether the number is a Krishnamurthy number. • then finally prints the result. Note: You are not allowed to use the built-in function math.factorial.arrow_forward(Financial application: compute future tuition)Suppose that the tuition for a university is $10,000 this year and increases 5% every year. Write a program that computes the tuition in ten years and the total cost of 4 years’ worth of tuition starting after the 10th year.arrow_forward
- (IN C LANGUAGE) Binary-Decimal / Decimal Binary . Between 0 and 255 a number will be decided randomly by computer. Then asks to user 3 times a random digit of binary value of the that number. If user enters wrong number for a digit program will select another random number and ask random times random digit. For example: Computer selected number as 163 ( Which is 10100011) What is the digit 2 (question 1/3) :User enter 1 CorrectWhat is the digit 4 (question 2/3) : User enter 0 CorrectWhat is the digit 7 (question 3/3) : User enter 0 CorrectUser finished the quest with 3 input .arrow_forward(Algebra: solve 2 * 2 linear equations) A linear equation can be solved using Cramer’s rule given in Programming Exercise 1.13. Write a program that prompts the user to enter a, b, c, d, e, and f and displays the result. If ad - bc is 0, report that “The equation has no solution.”arrow_forward(Python) Please write a program that creates steps. You are expected to take in a single positive integer which will be used as the number of steps in your staircase. The program only accepts integers greater than 0 and less than 500. If 0 is entered a message stating "Your staircase has no steps." and if the user enters a value greater than or equal to 500, a message stating "I can't build a staircase that tall." For all other values not within the valid range or not integers an "Invalid staircase size provided." will be displayed to the user. The program will always run only once for each user input. One thing to note, the messages should be the return string from your createSteps() function and printed from the calling function. Additional Requirements: 1. The very first step in the stair case will be left aligned and for each subsequent level the step will move above and to the right of the prior step. 2. There are no spaces after the right of any of the steps. 3. The bottom most…arrow_forward

Let (x1, y1) and (x2, y2) be the geographi- cal latitude and longitude of two points. The great circle distance between the two points can be computed using the following formula: d = radius * arccos(sin(x1) * sin(x2) + cos(x1) * cos(x2) * cos(y1 - y2)) Write a program that prompts the user to enter the latitude and longitude of two points on the earth in degrees and displays its great circle distance. The average earth radius is 6,378.1 km. The latitude and longitude degrees in the formula are for north and west. Use negative to indicate south and east degrees.arrow_forward
- [THIS IS NOT GRADED] The question mentions the bouncy program; this is the bouncy program I have written that computes the total distance traveled by the ball given initial height, bounciness index, and number of bounces: height = float(input("Enter the height from which the ball is dropped: ")) bounciness = float(input("Enter the bounciness index of the ball: ")) distance = 0 bounces = int(input("Enter the number of times the ball is allowed to continue bouncing: ")) for eachPass in range(bounces): distance += height height *= bounciness distance += height print('\nTotal distance traveled is:', distance, 'units.') I will attatch the pre-existing code that the question provided. Thank you for your help.arrow_forward(Electrical eng.) a. The voltage gain of an amplifier is given by this formula: voltagegain=[275 23 2 +0.5 f 2 ]n f is the frequency in Hz. n is the number of stages in the amplifier. Using this formula, write, compile, and run a C++ program to determine the value of the voltage gain for a four-stage amplifier operating at a frequency of 120 Hz. Your program should produce the following display: At a frequency of xxxxx hertz, the voltage gain is yyyyy Your program should replace xxxxx with the frequency and yyyyy with the voltage gain. b. Manually check the value your program produces. After verifying that your program is working correctly, modify it to determine the voltage gain of a 12-stage amplifier operating at a frequency of 9500 Hz.arrow_forward(C PROGRAMMING ONLY) 6. Deal or No Deal?by CodeChum Admin When I was a kid, I used to watch this TV game show, Deal or No Deal? In the game, there are different brief cases, each labeled with a number. Inside each brief case is an amount in Pesos and the goal is to guess which briefcase contains the smallest amount. In this program, instead of just finding the smallest amount, your task is to ask the user for an integer input and print the values in the array smaller than the inputted integer. Instructions: In the code editor, you are provided with an array with 100 elements.Your task is to ask the user for an integer input and then print all the elements in the array whose value is lesser than the inputted integer.Input 1.
