3. Implement a recursive function for a" in Python.

Please right your own code with some commentary.

Write a c++ code. Write a recursive function, vowelsCount that returns the number of vowels in a string. Output must needed.

Write a short recursive C++ program that will rearrange an array of int values so that all the even values appear before all the odd values.

in java Computing Powers, p(x,n)=xn1. Describe the definition of recursive function.oBase case(s)oRecursive case(s)2. Write the code

Write a recursive function double recSum(double array[], int count); that takes an int argument and returns the sum of count array entries. C++, please explain how the code works.

1) Write a recursive void function that has one parameter that is a positive integer and that writes out that number of asterisks (*) to the screen, all on one line. How do I do this in python?

Write a C++ program using classes and recursion functions to convert a number in a given base (the user enters the base - from 2 to 9) to a decimal number. The algorithm states that each successive digit in the number is multiplied by the base raised to the power corresponding to its position in the number. The low-order digit is in position 0. We sum together all of these products to get the decimal value. For example, in binary – base 2, if we have the binary number 111001, we convert it to decimal as follows: 1x 25+1x 24+1x23+0x22+0x 21+1x 2o=57 For a base 5 number, 14230: 1x54+4x53+2x52+3x51+0 x 50=1190 Validate your input. You should check for invalid digits and provide an informative error message to the user. This program requires you to use a recursive function for the conversion to decimal. Failure to do that will result in no points awarded.

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?

please solve in python and give code. thankzz

Write a recursive Python function named pgcd, to find and return the Greatest Common Divisor (GCD) of two numbers x and y passed in parameters. • Test it gcd (1234,4321) gcd (8192,192)

In C++: Explain and show how to use the recursive function int gcd (inta, int b).

I'm stuck on this question and I don't know how I should be approaching this. What should I do? Our focus is on pointers and dynamic arrays through C++
