Recursive function definition for “squares” function:

The recursive function definition for “squares” function is shown below:

//Function definition for "squares" function

int squares(int n)

{

      /* If "n" is less than or equal to "1" */

      if (n <= 1)

            //Returns "1"

            return 1;

      //Otherwise

      else

     /* Recursively call the "squares" function with subtracting the value of "n" by "1" and then add and multiplied by "n" */

            return (squares(n-1) + n * n);

}

Explanation:

The above function is used to compute the sum of the squares of numbers from “1” to “n”.

  • In this function, first check the value of “n”. If the value of “n” is less than or equal to “1”, then returns “1”.
  • Otherwise, recursively call the “squares” function with subtracting the value of “n” by “1” and then add and multiplied by “n”...

Write a recursive function definition for the following function: int squares(int n); //Precondition: n >= 1 //Returns the sum of the squares of numbers 1 through n. For example, squares(3) returns 14 because 12 + 22 + 32 is 14.
Write a recursive function that computes the sum of the digits in an integer. Use the following function header: def sumDigits(n):For example, sumDigits(234) returns Write a test program that prompts the user to enter an integer and displays its sum.
Problem: Recursive Power Method Design a python function that uses recursion to raise a number to a power. The function should accept two arguments: the number to be raised, and the exponent. Assume the exponent is a nonnegative integer. Write the main() function to input the required parameters as shown in thesample input/output.   Sample Output:Average number of words per line: 26.0Enter a number: 2Enter a positive whole number between 1 and 100: 102.0 raised to the power of 10 is 1,024.00
