//#define int long long to prevent the overflow
Thankyou so much
now i feel kind of pathetic
i made sum variable as a long long but forgot to make my vector as long long
AC
I think problem was just in prefix sum array. I changed it to long long and fixed the indexing it worked.
vi is vector, causing overflows while you compute the prefix sum
