Appreciate the effort man. Nice video and very helpful. Keep it up.
thanks man , i always try my best .
I solved that question during the contest and I feel there is no digit dp in it ā¦
brother for your comment āi feel there is no digit dp in itā i can say only one thing , just because you solved it one way doesnāt means it canāt be solved other ways.

Most of the people, solved it without using digit-dp, you can check the submissionsā¦so I guess, I am favouring the majority hereā¦I agree there is digit-dp, but not necessarily as it will get hard for newcomers and intermediates un-necessarilyā¦so I tried to explain you thatā¦in the videoā¦do mentionā¦that some implementation also works for this problem 
if there are more than one ways to do it (which is the case most of the times) i always mention it in the video.
And i know this can be solved using other approaches as well (most probably using Combinatorics , but since i am not good at it i can not explain it through that).
BTW what was your approach?

My approach is to traverse the string three times and add numbers like (10+100+etcā¦). No combinatorics as well !
