Daily Challenge #100

Welcome to 100th Daily Challenge [image] Thanks @peter for starting this and thanks to all those who participated either as making challenges or solving them . Also a big shout-out again to @peter for the above artwork The Challenge Sum of Digits : The challenge is to Kode procedure for finding the sum of digits of a given number until the sum we get is a single digit. Input A n digit non-negative number Output A single digit…

While explaining the logic to my friends I found out that there is a little problem in it.

Logic given by @pavi2410 and later used by me too will not return correct value for 0 which makes mine and pavi solutions invalid and @WatermelonIce the real winner.
