Hi, maybe I am confused by what constitutes an hourglass...but wouldn't 15 be the largest hourglass sum for this test case? However the expected output is 13.

1 1 1 0 0 0
0 1 0 0 0 0
1 1 1 0 0 0
0 9 2 -4 -4 0
0 0 0 -2 0 0
0 0 -1 -2 -4 0
the hourglass you bolded out is 1 + 1 + 9 + 2 = 13 you do not add the two outer 1's in the middle line with the three 1's above the line with 9
Thank you. I feel really stupid reading my comment now. I must not have actually added the numbers manually.
Thanks for the question, though. I was running into the same issue, and then after reading, was like, 'duh!'
yeah same here.
