Display "Cast your vote for Chess Team Captain."
Display "Would you like to nominate Lisa or Tim?"
Input choice

While choice != "Lisa" AND choice != "Tim"
Display "Please enter Lisa or Tim."

- The program in the Programming Example: Fibonacci Number does not check whether the first number entered by the user is less than or equal to the second number and whether both the numbers are non-negative. Also, the program does not check whether the user entered a valid value for the position of the desired number in the Fibonacci sequence. Rewrite that program so that it checks for these things.arrow_forwardPython Coding (on PyCharm Community Edition) WHAT COLOUR SQUARE PART 1 - Positions on a chess board are identified by a letter and number combination. See diagram. The letter refers to the column and the number refers to the row : ** MUST USE IF / ELIF / ELSE or some version of it for full marks. Do not use multiple IF statements unless you are nesting *** Write a program that reads the position (row and column) and tells the user which colour it will be. Do this twice. For example, if the user enters g3 - it should tell you BLACK. You can use the modulus for this question or lists - we have done similar work in this course. Create a mathematical formula to work out the position and colour. * The user should be able to input EITHER upper or lowercase.arrow_forwardUse this table to convert digits to barcode representation and vice-versa; each digit is represented in 5 characters; so 1 will be represented as 00011; as 0 is represented as half bar (:) and 1 is a full bar (1) ; 1 will be represented as :::|| ; similarly 9 is 10100 and will be represented as |:|:: Write a program that asks the user for a ZIP code and prints the bar code. Use : for half bars, | for full bars. For example, 95014 becomes ||:|:::|:|:||::::::||:|::|:::||| Your program should also be able to carry out the opposite conversion: Translate bars into their ZIP code, reporting any errors in the input format or a mismatch of the digits. javaarrow_forward
- The following program contains an error. It should only print "You answered heads" when the user enters "h" or "H", not when they enter "t" or "T". Rewrite the program in the space below to fix the error.arrow_forwardWrite algorithms to solve different programming problems using flowchart and pseudo-code. Problem: The program will display the following when run: 1. Display Pass/Fail Data 2. Display Final Grade Classification 3. Display Mean and Median Score Call the following function when the user selects from the menu: 1. Determine the number of students who passed (>=75%) and failed (<75%). Plot also the pass/fail data using a pie chart. 2. Classify and plot (using bar graph) the final grades based on the following: - Expert (95%-100%) - Competent (85%-94%) - Novice (75%-84%) - Beginner (<75%) 3. Calculate the mean and median final grade. Plot the mean and median score with the plot of all the final grades. Create an algorithm for the programming problem above using pseudo-code or flowchart.arrow_forwardodify the guessing-game program so that the user thinks of a number that the computer must guess. The computer must make no more than the minimum number of guesses, and it must prevent the user from cheating by entering misleading hints. Use I'm out of guesses, and you cheated and Hooray, I've got it in X tries as your final output. (Hint: Use the math.log function to compute the minimum number of guesses needed after the lower and upper bounds are entered.) this is what I got so far: ============================================ import random import math smaller = int(input("Enter the smaller number: ")) larger = int(input("Enter the larger number: ")) maxattempt = math.ceil(math.log(larger - smaller)) count = 0 while count != maxattempt: count += 1 guess = int((smaller + larger) / 2) print(smaller, larger) print("Your number is: ", guess) hlp = input("Enter =, <, or >: ") if hlp == '>': smaller = guess + 1 elif hlp == '<':…arrow_forward
- Programming language: c++ (1) Prompt the user for a string that contains two strings separated by a comma. Examples of strings that can be accepted: Jill, Allen Jill , Allen Jill,Allen Ex: Enter input string: Jill, Allen (2) Print an error message if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings. Ex: Enter input string: Jill Allen Error: No comma in string. Enter input string: Jill, Allen (3) Extract the two words from the input string and remove any spaces. Store the strings in two separate variables and output the strings. Ex: Enter input string: Jill, Allen First word: Jill Second word: Allen (4) Using a loop, extend the program to handle multiple lines of input. Continue until the user enters q to quit. Ex: Enter input string: Jill, Allen First word: Jill Second word: Allen Enter input string: Golden , Monkey First word: Golden Second…arrow_forwardCreate a new version of the program below that uses Boolean expressions for making the required decisions. Simplify the selection statements as much as possible. # Entering the sides of triangle a = int(input("Enter the length of first side :"))b = int(input("Enter the length of second side :"))c = int(input("Enter the length of third side :")) # CHECKING WHETHER TRIANGLE IS VALID OR NOT if(a + b >= c): if(a + c >= b): if(b + c >= a): print("Triangle is Valid") print("Perimeter is:",a+b+c) else: print("Triangle is Invalid")arrow_forwardDesign a program that asks the user for a series of names (in no particular order). After the final person’s name has been entered, the program should display the name that is first alphabetically and the name that is last alphabetically. For example, if the user enters the names Kristin, Joel, Adam, Beth, Zeb, and Chris, the program would display Adam and Zeb. This is to be done in Python.arrow_forward
- In Coral Language 3.22 LAB: Loops: Countdown until matching digits Write a program that takes in an integer in the range 20-98 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical. Ex: If the input is: 93 the output is: 93 92 91 90 89 88 Ex: If the input is: 77 the output is: 77 Ex: If the input is: 9 or any number not between 20 and 98 (inclusive), the output is: Input must be 20-98 For coding simplicity, follow each output number by a space, even the last one. Use a while loop. Compare the digits; do not write a large if-else for all possible same-digit numbers (11, 22, 33, …, 88), as that approach would be cumbersome for large ranges.arrow_forwardThe following are two examples of the program when it runs. <br> Example 1: Assume your input box contains: 2 16 2.5 6 3 Enter amount of lemon juice (in cups): Enter amount of water (in cups): Enter amount of agave nectar (in cups): How many servings does this make? Lemonade ingredients - yields 6.0 servings 2.0 cup(s) lemon juice 16.0 cup(s) water 2.5 cup(s) agave nectar How many servings would you like to make? Lemonade ingredients - yields 3.0 servings 1.0 cup(s) lemon juice 8.0 cup(s) water 1.25 cup(s) agave nectararrow_forwardCreate a new version of the program below that uses Boolean expressions (not true of false) for making the required decisions. Simplify the selection statements as much as possible. # Entering the sides of triangle a = int(input("Enter the length of first side :"))b = int(input("Enter the length of second side :"))c = int(input("Enter the length of third side :")) # CHECKING WHETHER TRIANGLE IS VALID OR NOT if(a + b >= c): if(a + c >= b): if(b + c >= a): print("Triangle is Valid") print("Perimeter is:",a+b+c) else: print("Triangle is Invalid") OUTPUT HAS TO BE Enter three edges: 1,1,1 The perimeter is 3 Enter three edges:1,3,1 The input is invalidarrow_forward
