In the maximum gold path question, could someone explain why the expected answer is 60 for the following test case?
[[1,0,7,0,0,0],[2,0,6,0,1,0],[3,5,6,7,4,2],[4,3,1,0,2,0],[3,0,5,0,20,0]]

My code outputs 58, but I do not know where to start debugging because I'm getting 58 when calculating by hand too.
