Test Status Code Input and Output
1   Pass
x = [1 0 -1 3 2 -3 1]; window = 2; y_correct = 3; assert(isequal(sum_positive(x, window),y_correct))

t = 1 y = 1 t = -1 t = 2 y = 2 t = 5 y = 3 t = -1 t = -2

2   Pass
x = [1 0 -1 3 2 -3 1]; window = 3; y_correct = 3; assert(isequal(sum_positive(x, window),y_correct))

t = 0 t = 2 y = 1 t = 4 y = 2 t = 2 y = 3 t = 0

3   Pass
x = [1 0 -1 3 2 -3 1]; window = 4; y_correct = 4; assert(isequal(sum_positive(x, window),y_correct))

t = 3 y = 1 t = 4 y = 2 t = 1 y = 3 t = 3 y = 4

4   Pass
x = [1 0 -1 3 2 -3 1 1 1 1 1 1]; window = 2; y_correct = 8; assert(isequal(sum_positive(x, window),y_correct))

t = 1 y = 1 t = -1 t = 2 y = 2 t = 5 y = 3 t = -1 t = -2 t = 2 y = 4 t = 2 y = 5 t = 2 y = 6 t = 2 y = 7 t = 2 y = 8
