Laboratory $12$ Consists of:

Four Recursion Problems to Solve

$1.$ Recursive Sum of Numbers

$2.$ Recursive Power Method

$3.$ Make the Count Characters in String recursive algorithm case

insensitive

$4.$ Find largest number in a list of integers

Sum of Numbers

$$ Design a function that accepts an integer argument and returns the sum of all

the integers from $1$ up to the number passed as an argument.

$$ For example, if $50$ is passed as an argument, the function will return the sum

of $1,2,3,4,...50.$

$$ Use recursion to calculate the sum.

$$ Call your program: YourName$\_$SumOfNum.py

$$ If you are doing Lab$12$ synchronously, ask the Instructor to check out your

SumOfNum program to receive full credit.

$$ If you are doing Lab$12$ asynchronously, then submit YourName$\_$SumOfNum.py

to Canvas.

$$ After you have solved this problem, then do the second one.
