Print statement

A statement in a program that displays the variables, object, or text to the output device (screen) is known as a print statement. The print statement consists of a function that forwards the output to standard output devices such as printers, monitors, etc. Depending on the programming language, the syntax of the print statement differs. The print statement allows the user to print the values of multiple variables in a single statement; however, the variables are separated using a separator (comma, plus, etc,).

python3 Write a recursive function called is_palindrome(string) that takes a string parameter and checks if it is a palindrome ignoring the spaces, if any, and returns True/False. Sample output:>>> print(is_palindrome("never odd or even"))True>>> print(is_palindrome("step on no pets"))True
A palindrome is a sentence that contains the same sequence of letters reading it either forwards or backwards. A classic example is '1\.ble was I, ereI saw Elba." Write a recursive function that detects whether a string is apalindrome. The basic idea is to check that the first and last letters of thestring are the same letter; if they are, then the entire string is a palindromeif everything between those letters is a palindrome.There are a couple of special cases to check for. If either the first orlast character of the string is not a letter, you can check to see if the restof the string is a palindrome with that character removed. Also, when youcompare letters, make sure that you do it in a case-insensitive way.Use your function in a program that prompts a user for a phrase andthen tells whether or not it is a palindrome. Here's another classic fortesting: '1\. man, a plan, a canal, Panama!"
Please assist me with these questions.(for the 1st part just complete the bolded area. All other areas have been completed. Then complete the 2nd part 1. Devise an algorithm to receive a positive number, n, and output all prime numbers that are smaller than n and have the digit 5. For example, if n is 100, the program should output 5, 53 and 59. Your solution should have a main algorithm and two sub-algorithms, let's call them prime(num) and has5(num). Trace your algorithm and sub-sub-algorithm for the input 15. You should provide pre- and post-conditions for all your 3 (sub)algorithms. Now, let's trace this algorithm for the input n = 15: For i = 2 to 14, we check if i is prime and if i contains the digit 5. The prime numbers less than 15 are 2, 3, 5, 7, 11, 13. Among these, only 5 contains the digit 5. So, the output for n = 15 is [5]. 2. I also need help with creating JavaScript code for the flowchart provided below.

please code in python Write a recursive function to add a positive integer b to another number a, add(a, b), where only the unit 1 can be added, For example add(5, 9) will return 14. The pseudocode is: # Base case: if b is 1, you can just return a + 1 # General case: otherwise, return the sum of 1 and what is returned by adding a and b - 1.

Practicing Loops. Einstein Private Elementary school has three classes in each of its 9 grades. 27 classes in total. It has kindergarten (grade 0) though 8th grade. The school allows parents to pay tuition over the nine-month school year. Tuition for kindergarten is $90 dollars every month. Tuition for the other grades is $50 times the grade level every month. (1st grade is $50 a month, second grade is $100 a month, etc.) Design a programming solution that outputs nine tuition payment bills for each of the 27 classrooms. Each bill must contain the grade number (0 through 8), the classroom number (1 through 3), the month (1 through 9) and the amount of the tuition due. Your output should look something like: Grade Classroom Month Tuition 0 1 1 90 0 1 2 90 0 1 3 90 0 1 4 90 ... 8 3 7 400 8 3…

5. Given an integer n, you need to find the digital root of that integer using a recursive function. If n has only 1 digit, then its digital root is n. Otherwise, the digital root is equal to the digital root of the sum of the digits of n. The process continues until a single-digit number is reached. For example, digital_root of 576 is calculated as: digital_root (576) = 5+7+ 6 = 18 digital_root (18) = 1 +8=9 digital_root (9) = 9 Programming Language :- C So, the digital root of 576 is 9
Good Programming practices help in improving programs readability and understandability both for a programmer and for a general user. What changes would you make in the following program, written by a beginner, keeping in view the good programming practices. You are also required to write the output of the program if a user wants to find factorial of number 6. Note: The Program finds/calculates factorial of a number using a user defined recursive function. #include<iostream> using namespace std; int f(int n); int main() { int n; cout << "Enter: "; cin >> n; cout << "Answer = " <<factorial(n); return 0; } int f(int n) { if(n > 1) return n * f(n - 1); else return 1; }
