- Cyclops numbersdef is_cyclops(n):A nonnegative integer is said to be a cyclops number if it consists of an odd number of digits so that the middle (more poetically, the “eye”) digit is a zero, and all other digits of that number are nonzero. This function should determine whether its parameter integer n is a cyclops number, and return either True or False accordingly n Expected result 0 True 101 True 98053 True 777888999 False 1056 False 675409820 FalseQ3: write a program that uses a function to display the following shape: 1 49 1 49 1 49Create a flowchart that uses an array that contains valid names for 10 cities in Michigan namely: Acme, Albion, Detroit, Watervliet, Coloma, Saginaw, Richland, Glenn, Midland and Brooklyn. You ask the user to enter a city name; your program then searches the array for that city name. If it is not found, the program should print a message that informs the user the city name is not found in the list of valid cities in Michigan.
- Code in Python: Your hangman game should be broken into appropriate functions, contain a main function, anddo the following:1. The program should randomly select a word from the list: kangaroo, capybara, wombat,koala, wallaby, quokka, platypus, dingo, kookaburra2. Repeatedly prompt the user to guess a letter.3. Validate the input4. All guessed letters should be stored in a two-dimensional list (from problem 2). If thenumber of times a letter has been guessed is greater than 1, then the user should benotified that they have already guessed this letter and prompted to guess a differentletter. The hangman won’t update (grow) if the same incorrect letter is guessed multipletimes.5. The word should be printed where all correctly guessed letters are revealed, and allunguessed letters are replaced with underscores6. A hangman reflecting the number of incorrect guesses should be printed7. If all the letters in the word are guessed, then the user wins. If the hangman / number ofincorrect…A left rotation operation on an array of size shifts each of the array's elements unit to the left. Given an integer, , rotate the array that many steps left and return the result. Example After rotations, . Function Description Complete the rotateLeft function in the editor below. rotateLeft has the following parameters: int d: the amount to rotate by int arr[n]: the array to rotate Returns int[n]: the rotated array Input Format The first line contains two space-separated integers that denote , the number of integers, and , the number of left rotations to perform.The second line contains space-separated integers that describe . Constraints Sample Input 5 4 1 2 3 4 5 Sample Output 5 1 2 3 4 Explanation To perform left rotations, the array undergoes the following sequence of changes:(Numerical) Write and test a function that returns the position of the largest and smallest values in an array of double-precision numbers.
- (Numerical) Using the srand() and rand() C++ library functions, fill an array of 1000 floating-point numbers with random numbers that have been scaled to the range 1 to 100. Then determine and display the number of random numbers having values between 1 and 50 and the number having values greater than 50. What do you expect the output counts to be?(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.(Numerical) Given a one-dimensional array of integer numbers, write and test a function that displays the array elements in reverse order.
- (Electrical eng.) a. An engineer has constructed a two-dimensional array of real numbers with three rows and five columns. This array currently contains test voltages of an amplifier. Write a C++ program that interactively inputs 15 array values, and then determines the total number of voltages in these ranges: less than 60, greater than or equal to 60 and less than 70, greater than or equal to 70 and less than 80, greater than or equal to 80 and less than 90, and greater than or equal to 90. b. Entering 15 voltages each time the program written for Exercise 7a runs is cumbersome. What method could be used for initializing the array during the testing phase? c. How might the program you wrote for Exercise 7a be modified to include the case of no voltage being present? That is, what voltage could be used to indicate an invalid voltage, and how would your program have to be modified to exclude counting such a voltage?Write a program that reads in a line consisting of a students name, Social Security number, user ID, and password. The program outputs the string in which all the digits of the Social Security number and all the characters in the password are replaced by x. (The Social Security number is in the form 000-00-0000, and the user ID and the password do not contain any spaces.) Your program should not use the operator [] to access a string element. Use the appropriate functions described in Table 7-1.(Numerical) a. Define an array with a maximum of 20 integer values, and fill the array with numbers input from the keyboard or assigned by the program. Then write a function named split() that reads the array and places all zeros or positive numbers in an array named positive and all negative numbers in an array named negative. Finally, have your program call a function that displays the values in both the positive and negative arrays. b. Extend the program written for Exercise 6a to sort the positive and negative arrays into ascending order before they’re displayed.
