    SAMPLE INPUT - 1
arr = [12, -1, -7, 8, -15, 30, 18, 28]
k = 3
SAMPLE OUTPUT - 1
[-1, -1, -7, -15, -15, 0]
EXPLANATION
All window of K size will be,

[12, -1, -7] = First negative is -1
[-1, -7, 8] = -1
[-7, 8, -15] = -7
[8, -15, 30] = -15
[-15, 30, 18] = -15
[30, 18, 28] = 0

Hence the final result will be [-1, -1, -7, -15, -15, 0]
