Write c++ recursive function
3. A function that takes an integer, and returns the product of the digits, so the input 1989 would return 1∗9∗8∗9 = 648
4. A function that does the above repeatedly, taking a number and computing the product
of it’s digits until you get a single digit number: so on input 1989 it would go 1989→648→192→18→8 and return 8. (Note, you can use the previous functions if you want.
#include <iostream> using namespace std; int product(int n) { if (n < 10) { return n; } else { return (n % 10) * product(n / 10); } } int product_digit(int n) { if (n < 10) { return n; } else { return product_digit(product(n)); } } int main() { cout << product(1989) << endl; cout << product_digit(1989) << endl; return 0; }

****python**** Q1. Write a recursive function that returns the sum of all numbers up to and including the given value. This function has to be recursive; you may not use loops! For example: Test Result print('%d : %d' % (5, sum_up_to(5))) 5 : 15 Q2, Write a recursive function that counts the number of odd integers in a given list. This function has to be recursive; you may not use loops! For example: Test Result print('%s : %d' % ([2,...
In Python 3 (2.5 pts] Write the recursive function thirtyTwos(n) that takes an integer greater or equal to 0 and returns an integer that represents the number of times that a 2 directly follows a 3 in the digits of n. Hint: The % and // operations from sumDigits could be helpful here >>> thirtyTwos (132432601)
need help with python ( no loops used please!) Write a recursive function named sum_digits that takes a given a non-negative integer N and returns the sum of its digits. Hint: Mod (%) by 10 gives you the rightmost digit (126 % 10 is 6), while doing integer division by 10 removes the rightmost digit (126/10 is 12). This function has to be recursive; you are not allowed to use loops to solve this problem! This function takes in one...
Write a Python function, called counting, that takes two arguments (a string and an integer), and returns the number of digits in the string argument that are not the same as the integer argument. Include a main function that inputs the two values (string and integer) and outputs the result, with appropriate labelling. You are not permitted to use the Python string methods (such as count(), etc.). Sample input/output: Please enter a string of digits: 34598205 Please enter a 1-digit...
Write a java recursive method digitMatch that takes two nonnegative integers as parameters and that returns the number of digits that match between them. Two digits match if they are equal and have the same relative position starting from the end of the number (i.e., starting with the ones digit). In other words, the method should compare the last digits of each number, the second-to-last digits of each number, the third-to-last digits of each number, and so forth, counting how...
Write a recursive function named arithmeticSum that takes a positive integer parameter n and returns the sum of the integer numbers from 1 to n Please write in C++
1.Write a function called high_point that takes a list of integers and returns True if there exists a value in the list that is bigger than the values immediately before and after it in the list. Your function must return False if no such value exists. The values in the beginning and the end of the list cannot be high points. (20 points) Test Cases: print(high_point([2,5,8,9,7,9])) True print(high_point([2,5,6,6,3])) False print(high_point([2,5,8,21,22])) False 2. Write a while loop to repeatedly ask for...
(Java) - Write a recursive program that takes array of number and an integer, and returns true if the integer is in the array or false if the integer is not in the array
1. DOES A DIGIT APPEAR IN AN INTEGER, Write a recursive function appears(n,i) that returns true if the digit i appears in the positive (base 10) integer n, false if it does not in c++. ex. Enter a positive integer: 54321 Enter a digit: 7 The digit 7 does NOT appear in the integer 54321. 2. IS AN INPUT STRING A PALINDROME? A palindrome is a string in which the letters are the same in both directions, disregarding capitalization and...
CH Question 1. Implement a recursive method fibo that takes an integer num as a parameter and returns the nth Fibonacci number. Fibonacci sequence: 1, 1, 2, 3, 5, 8, 13, ... is an infinite sequence, where first 2 numbers are 1 and every subsequent number is equivalent to the sum of the previous two. Question 2. Implement a recursive method mult that takes two positive integer parameters, x and y and returns their product For example mult(2,3) returns 6....
