In this exercise, you will create a function that takes an integer, i. With it you must do the following:

• Find all of its multiples up to and including 100,

• Then take the digit sum of each multiple (eg. 45 -> 4 + 5 = 9),

• And finally, get the total sum of each new digit sum.

Note: If the digit sum of a number is more than 9 (eg. 99 -> 9 + 9 = 18) then you do NOT have to break it down further until it reaches one digit.

Example (if i is 25):

Multiples of 25 up to 100 --> [25, 50, 75, 100]

Digit sum of each multiple --> [7, 5, 12, 1]

Sum of each new digit sum --> 25

If you can, try writing it in readable code.
