Explain the line "sum=(sum+n)%n"

#1

you said this code works for -ve sums too.
Then why it fails if i take array as -10, -5, 5, 2, 1 .

#2

hello @alok.maurya

first u need to convert sum in between range of -n to n
for that first take mod of sum with n
i.e sum=sum%n;

now use mod property ->
sum=(sum+n)%n -> // this is done to make mod positive

if u add these two lines then ur code will work for evry cases
