Hello @khushipriya681,

  1. To convert the negative numbers to positive, you have to first limit them in a range from 0 to n-1
    Reason:
    sum=(sum+n)%n; would not work for the case when the sum < -n

  2. The case when prefix[i]*(prefix[i]-1) is a large value (say long)
    prefix is of type int.
    So,
    product of int and int will result into int.

I have modified your code:

Hope, this would help.
Give a like, if you are satisfied.
