Given a vector:
[1 0 -1 3 2 -3 1]
and a window of 2,
A sliding window would find:
1 + 0 = 1 0 - 1 = -1 -1 + 3 = 2 3 + 2 = 5 2 - 3 = -1 -3 + 1 = -2
Meaning that three of the windows were positive.
Given a vector and a window, how many of the windows sum to be positive, not zero or negative?

I think test suite 3 produces 4 positives, not 3.

Test suite 3 doesn't seem to be correct. Total windows possible in this case is 2. How can number of positive windows be greater than that. Someone please clarify.

Window is how many numbers you are adding together for every position
