Write a recursive function that calculates the sum 11 22 33 ... nn, given an integer value of nin between 1 and 9. You can write a separate power function in this process and call that power function as needed:

The function in Python is as follows:

def sumDig(n):

if n == 1:

 return 11

else:

 return n*11 + sumDig(n - 1)

Explanation:

This defines the function

def sumDig(n):

This represents the base case (where n = 1)

if n == 1:

The function returns 11, when it gets to the base case

 return 11

For every other value of n (n > 1)

else:

This calculates the required sum recursively

 return n*11 + sumDig(n - 1)

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).
