6. Write a program that reads in an integer and breaks it into a sequence of individual digits. For example, the input 16384 is displayed as 16384 You may assume that the input has no more than five digits and is not negative.
6. A palindrome is a number or text phrase that reads the same backwards or forwards. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611. Write a program that reads a 5 digit integer and determines whether it is a palindrome. Hint: One way to do this is to use division (/) and modulus (%) operators to separate the number into individual digits.

PROBLEM:Write a program that prompts the user to input any digit then swap the position of the first and the last digit. Next, the user will be prompt to select what arithmetic operation he/she want to employ on the first and last digit based on the following choices: 1. Sum of their square 2. Product of their square root 3. Square of their product The output will display the result of the arithmetic operation followed by the digit with a swapped position of “first” and “last” digit. Then finally display the equivalent uppercase alphabet for the first digit and lowercase alphabet for the last digit respectively after swapping. Note: 1. If the last digit of the inputted digit from the user is zero, it must display that there is no equivalent alphabet for that digit. 2. If the user chooses arithmetic operation No.2, format the output to three decimal places
Three numbersa. Write a program that reads three numbers and prints “all the same” if they are allthe same, “all different” if they are all different, and “neither” otherwise.b. Write a program that reads three numbers and prints “increasing” if they are inincreasing order, “decreasing” if they are in decreasing order, and “neither”otherwise. Here, “increasing” means “strictly increasing”, with each value largerthan its predecessor. The sequence 3 4 4 would not be considered increasing.c. Repeat part b. but before reading the numbers, ask the user whetherincreasing/decreasing should be “strict” or “lenient”. In lenient mode, thesequence 3 4 4 is increasing and the sequence 4 4 4 is both increasing anddecreasing
1. Write a program that does the following: - reads an unspecified number of integers - determines how many positive and negative values have been read - computes the total and average of the input values (not counting zeros). Your program ends with the input 0. Display the average as a floating-point number. If the entire input is 0, the program displays "No numbers are entered except 0". Here is a sample run: Enter integers ending with e: 1 2 -1 3 e The number of positives is 3 The number of negatives is 1 The total is 5 The average is 1.25 2. A pentagonal number is defined as n(3n-1)/2 for n= 1, 2, ..., etc.. Therefore, the first few numbers are 1, 5, 12, 22, .... Write a method with the following header that returns a pentagonal number: public static int getPentagonalNumber(int n) For example, getPentagonalNumber(1) returns 1 and getPentagonalNumber(2) returns 5. Write a test program that uses this method to display the first 100 pentagonal numbers with 10 numbers on each line.…
..5-- I have a python programing question In 1937, a German mathematician named Lothar Collatz formulated an intriguing hypothesis (it still remains unproven) which can be described in the following way: 1. take any non-negative and non-zero integer number and name it c0; 2. if it's even, evaluate a new c0 as c0 ÷ 2; 3. otherwise, if it's odd, evaluate a new c0 as 3 × c0 + 1; 4. if c0 ≠ 1, skip to point 2. The hypothesis says that regardless of the initial value of c0, it will always go to 1. Of course, it's an extremely complex task to use a computer in order to prove the hypothesis for any natural number (it may even need artificial intelligence), but you can use Python to check some individual numbers. Maybe you'll even find the one which would disprove the hypothesis. Write a program which reads one natural number and executes the above steps as long as c0remains different from 1(c0 != 1). Moreover, we'll add another task - we want you to count the steps needed to achieve the goal.…
Write a program that generates a plate number based on the user's answer to the following questions: 1. What is your favorite color of the rainbow (ROYGVIB)? a. Use the first letter of the chosen color as the first character of the plate number. b. Display "Invalid Input" and ask the user to re-enter his/her answer if the answer is not a valid color of the rainbow. 2. What is your month of birth? a. Use the last letter of the month as the second character of the plate number. b. Display "Invalid Input" and ask the user to re-enter his/her answer if the answer is not a valid month. 3. What is your first name? a. Use the third letter of the first name as the third character of the plate number. No need to include the second name if you have a second name. Make sure to use "cout" and "cin" to collect the necessary inputs from the user. For the number section: 1. Ask the user his/her age and use the age as the first and second digits of the plate number. a. Display "Invalid Input" and ask…

f. A laborant in a laboratory does a number of antigen tests in one day. Write a program that simulates the number of antigen tests done in a day in a laboratory, displays the number of positives and negatives, and calculates the % of positives in one day. Your program needs to first generate a random number that will show the number of tests done in a day. One laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one). Then for each of the tests, your program needs to generate a random number to show whether they are positive or negative. In order to write this program, you need to have the following three functions used by the main function: test result (void): This function generates a test result. It should randomly return either one or zero. 1 means positive test result and 0 means negative test result. float positive percentage (int,int) : This function takes the total number of positives and the total number of tests and returns the % of positives.…
A number in base 2 (binary) is a number such that each of its digits is 0 or 1. To convert from binary to decimal (base 10), the digits starting from the right are multiplied by powers of 2 (starting at 0) and added. For example, the value in decimal of 10011 is calculated as follows: 1 ×2º+ 1 ×21+ 0 ×2²+ 0 ×2³+ 1 ×24=19 Write a program that reads from the user a 5-digit integer representing a value in binary and displays its equivalent value in decimal. Note that if the user enters an integer which digits are other than 0 or 1, the program displays a message stating that the number is not valid. Sample Run 1: Enter a 5-digit integer made of Os and ls: 10011 10011 in decimal is 19 Sample Run 2: Enter a 5-digit integer made of Os and 1s: 13001 13001 is not valid
