回了一篇十几年前的文章 (
#1EJC0a1a)
因为这个星期 Project Euler 的题目就是这个 XD
https://projecteuler.net/problem=879
不过这题有把画过中点後可以跳连算进去, 所以比我们当年算的还多很多
那当然 3x3 的一定有很多人 (用各种方式) 算过了, 所以这题问的是 4x4
==
然後好在我先用 Mathematica 写, 虽然要跑 30 秒但至少答案是对的...

'You've sort of made up for it tonight,' said Harry. 'Getting the
sword. Finishing the Horcrux. Saving my life.'
'That makes me sound a lot cooler then I was,' Ron mumbled.
'Stuff like that always sounds cooler then it really was,' said
Harry. 'I've been trying to tell you that for years.'
