I'm confused about the reason I can't pass this test, if anyone can notice what's the cause I would be grateful :)
here is the log :
:( blur correctly filters 3x3 image
Expected Output:
70 85 95
80 95 105
90 105 115
117 130 140
127 140 149
137 150 159
163 178 188 170 185 194 178 193 201
Actual Output: 70 85 95 80 95 105 90 105 115 117 130 140 127 140 149 137 150 159 163 200 188 170 185 194 178 193 201
