Hey do this

if(i>=1)
current_sum = cum_sum[j] + cum_sum[i-1];
else
current_sum= cum_sum[j] ;

i dont understand it where are you telling to insert it and how will it make any difference kindly edit the code and comment out mistake it would be easier to understand.
i have checked current sum array it was completely correct

Hey Sorry but I wont be able to edit your code right now
You have to use this instead of line 20 because when j=i and i=0 then you are trying to subtract cursum[-1] which will give you garbage value.
