Thank you, for such a clean explanation!

[prathmeshadsod]

I got some understanding after viewing second time...
We just care about unit digit , so we are checking greedily from i = 1 to i == 10
what minimum unit digits can we take and (nums - i * k) % 10 that means we got
our smallest i and we are free now to insert any number at tens or hundreds place
like digits to add .
And we want only size to return

Give this guy a Medal 🥇,
Suggestion : pls use digital pen
Doubt: if num would be greater then 100, still atmost 10 sets will be generated!!

Sanchit, I didn't really understand. It's my bad though because others were able to get it. How could you split it into 9 + 10X ? Can you please let me know

Also, recommendation for connecting digital pen to Mac. Well, you can use it if you can install third party drivers. If you are blocked from installing those, then the pen would just behave as a mouse.

how this T - ( K * i ) = 10 * ( x+y+z+....+..+..k-times) formula came ? please reply

[mayankkumarthakur]
