Divisible subarrays

#1

sir I do not understand the logic here! …please explain me because I have watched the video many times and I could not get it.
and the size of array was 5, do you make it as 6 and initialize the first element as 0 at index 0?

#2

hello @mzk1994 what part of the code you haven’t understood.

#3

thanks for your response
sir I understand till you reach the cumulative array %n and then you have used a formula (2c2)or something like that?
and sir the array size was 5 why does the size become 6 in the cumulative array and in cumulative array%n??

#4

hello @mzk1994 yes right .
the size becomes 6 in the last step because there can be remainder from 0 to 6 any number could be there as a remainder between this range.
this is the reason.
