(Factorials) The factorial function is used frequently in probability problems. The factorial of 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

- Urgent help needed!#!arrow_forwardFind the error(s) in the following code: (6)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
- Hi! I need help with this homework! (it is C prgramming ) Thank youarrow_forward5. (Algebra: solve 2 X 2 linear equations) You can use Cramer's rule to solve the following 2 X 2 system of linear equation: ax + by = e cx + dy = f ● x = ed - bf bc ad y = af - ec ad bc - Write a program that prompts the user to enter a, b, c, d, e, and f and display the result. If ad- bc is 0, report that The equation has no solution. Enter a, b, c, d, e, f: 9.0, 4.0, 3.0, -5.0, -6.0, -21.0 Enter x is -2.0 and y is 3.0 Enter a, b, c, d, e, f: 1.0, 2.0, 2.0, 4.0, 4.0, 5.0 Enter The equation has no solutionarrow_forward(Bar-Chart Printing Program) One interesting application of computers is drawing graphsand bar charts. Write a program that reads five numbers (each between 1 and 30). For each numberread, your program should print a line containing that number of adjacent asterisks. For example,if your program reads the number seven, it should print *******.arrow_forward
- (Financial: credit card number validation) Credit card numbers follow certain pat- terns. A credit card number must have between 13 and 16 digits. It must start with: 4 for Visa cards 5 for Master cards 37 for American Express cards 6 for Discover cards In 1954, Hans Luhn of IBM proposed an algorithm for validating credit card numbers. The algorithm is useful to determine whether a card number is entered correctly or whether a credit card is scanned correctly by a scanner. Credit card numbers are generated following this validity check, commonly known as the Luhn check or the Mod 10 check, which can be described as follows (for illustra- tion, consider the card number 4388576018402626): 1. Double every second digit from right to left. If doubling of a digit results in a two-digit number, add up the two digits to get a single-digit number. 4388576018402626 → 2 * 2 = 4 → 2 * 2 = 4 → 4 * 2 = 8 → 1 * 2 = 2 6 * 2 = 12 (1+ 2 = 3) → 5 * 2 = 10 (1+ 0 = 1) → 8 * 2 = 16 (1 + 6 = 7) → 4 * 2 = 8arrow_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 printSteps() function and printed from the calling function. Additional Requirements: The very first step in the staircase will be left-aligned and for each subsequent level, the step will move above and to the right of the prior step. There are no spaces after the right of any of the steps. The bottom-most row ends…arrow_forwardPython Programming Part 2 Direction: Use PYTHON to solve this problem. Description: This part tests for two things. The program must identify all resistors in series or in parallel with each other and calculate the equivalent resistance for each group of resistors. Recall that total resistance of resistors in series are added up while the total conductance of those in parallel are added up. Input Format: The first line of the input consists of 1 integer N which is the total number of resistors. The next N lines will consist of 3 strings and an integer R each separated by a space. The first string is the resistor name, the second and third strings are the node names where the resistor terminals are connected, and R is its resistance value. Output Format: One line for each group of resistors in series or parallel. Each line starts with a list of resistors arranged in lexicographical order (see Lexicographic order - Wikipedia) followed by their total resistance rounded off to the nearest…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(DEBUG AND MAKE A FLOWCHART OF THIS PROGRAM) // This pseudocode is intended to display// employee net pay values.
