What exactly do you call "similar to python" when the following is a program
written in it? Compared to that, even Perl is a wonder of readability...
m =: >@(0&{)
v =: >@(1&{)
h =: >@(2&{)
qu =: >@(3&{)
z =: [EMAIL PROTECTED]:
ret =: |[EMAIL PROTECTED]:
init =: z;z;z;i.
f1m =: (m,[EMAIL PROTECTED]);v;h;[EMAIL PROTECTED]
f5m =: (z;(v,{:@m);h;qu,[EMAIL PROTECTED]) @ (f1m^:5)
f1h =: (z;z;(h,{:@v);(qu,[EMAIL PROTECTED])) @ (f5m^:12)
f12h =: (z;z;z;qu,[EMAIL PROTECTED],{:@h) @ (f1h^:12)
perm =: qu @ f12h @ init
ord =: *./ @ (#&>"_) @ C.
days =: -: @ ord @ perm
