Sub Array(Sum of Sub Array)

#1

We have to find sum of sub array.
Input : -4 1 3 -2 6 2 -8 -9 4
output : 0 -2 4 6 -2 -11 …
I want to ask why the first element in output is 0, I think it should be -4 because when we output sub array, it prints first element and then goes out of loop then it prints -4 1 and so on…

#2

Yes…if you are computing the prefix sum…then it must be:
-4, -4+1, -4+1+3, …and so on
that is
-4,-3,0,-2,4,6,-2,-11…

#3

But i want to ask why it shows 0 first in output.
