How do we get the answer 1.78? Which angle do we rotate the star by at every step? My program outputs the following angles:

1.2309594173
0.9654637454
0.6737614519
0.5281218484
0.4721787343

which give the answer 3.8704851972

0.000000000
0.445561254
0.445561254
0.445561254
0.445561254

I think, your mistake that: "Each of the following n lines contains the vector of the attack". It mean, if vector of attack (0,0,-1), attack goes from (0,0,1). Good luck!
