- In C++ Write a recursive function called PrintNumPattern() to output the following number pattern. Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until 0 or a negative value is reached, and then continually add the second integer until the first integer is again reached. For this lab, do not end output with a newline. Ex. If the input is: 123 the output is: 12 9 6 3 0 3 6 9 12 #include <iostream> using namespace std; // TODO: Write recursive PrintNumPattern() function int main(int argc, char* argv[]) { int num1; int num2; cin >> num1; cin >> num2; PrintNumPattern(num1, num2); return 0;}Need help with this c++ problem Write a recursive function named lettersOnly that accepts a string str as a parameter and returns a string with the same characters as str, in the same order, but excluding any characters that are not alphabetic letters from A-Z, case-insensitive. For example, lettersOnly("{[[Friends, save $$$ with 'Geico'!!]]}") should return "FriendssavewithGeico".Write a recursive function that takes as a parameter a nonnegative integer and generates the following pattern of stars. If the nonnegative integer is 4, then the pattern generated is:********************Also, write a program that prompts the user to enter the number of lines in the pattern and uses the recursive function to generate the pattern. For example, specifying 4 as the number of lines generates the above pattern.
- need help Writing a recursive function, isPalindrome, to check if a string is a palindrome. Return true if the string is a palindrome; otherwise, return false. in javascript example isPalindrome('Kayak'); // => true i sPalindrome('NEVERODDOREVEN'); // => true i sPalindrome('Tacocat'); // => true isPalindrome('SELFLESS'); // => falseIn Kotlin, Write a higher-order function that takes two arguments and returns a String. The first argument is a String and the second is a function that takes a Char and returns a Boolean. Your function should return a String containing those of the characters in the original String for which the function returns true. Use a tail-recursive helper function. Remember to make sure you get the tail recursion right by using the tailrec annotation. Test the functionIn C programing Write a recursive function that returns the product of the digits of its integer input parameter, n. You may assume that n is non-negative. For example, productDigits(243) should return 24, since 2 x 4 x 3 = 24.int productDigits (int n) {
- In C++ Consider the following recursive function (Chapter 17, #9, modified) void recFun(int x) { if (x > 10) { recFun(x / 10); cout<< x % 10; } else cout<< x; } How can the code be modified so that the sum of all digits is printed?Write a recursive function that takes as a parameter a nonnegative integer and generates the following pattern of stars. If the nonnegative integer is 4, the pattern generated is as follows: **** *** ** * * ** *** **** Also, write a program that prompts the user to enter the number of lines in the pattern and uses the recursive function to generate the pattern. For example, specifying 4 as the number of lines generates the preceding pattern.c++ Write a recursive function that, given two strings, returns whether the first string is asubsequence of the second. For example, given hac and cathartic, you should return true, but givenbat and table, you should return false.
- Given two integers x snf y, the following recurrsive definition determined the greatest common divisor of x and y, Write gcd(xy). Write a recursive function, gcd, that takes two integers as parameters and returns the greatest commmon divisorof numbers.Also write a program to test your function. Write a recursive function,reverseDigits, that takes an integer as a parameter snd returns the number with the digits reversed. Also write a program to test your application.Write a recursive function called Mod which takes two positive integers argument (aand b) and returns a % b – the remainder of a dividing by b. You may not use a remainderoperator or built-in function.Write a recursive function, vowels, that returns the number of vowels in a string. Also, write a program to test your function.
