IAṢ⁼J$ jolly function on N:
IAṢ the increment list: get all the Increments, take their Absolute values, and Ṣort them
⁼ compare that to...
J$ range from 1 to len(N) -- this has an extra number, but that's fine because...
...the increment list is one shorter, and ⁼ will only compare that many values
Mengambil input sebagai angka yang dipisahkan koma dalam argumen pertama. Mengembalikan 1 jika urutannya riang, dan 0 jika tidak!

Mengambil input sebagai angka yang dipisahkan koma dalam argumen pertama. Tidak menghasilkan apa-apa jika daftar adalah urutan jolly jumper, dan sesuatu jika tidak.
Menambahkan baris ini membuatnya bekerja dengan spesifikasi keras:

Menghidupkan nomor yang dipisahkan ruang stdin, dan menampilkan "Jolly" atau "Not jolly".
Penjelasan:
LRṖḟIA$ jolly function:
LRP make a range (R) from 1 to the input length (L), popping off (P) the last number to make it 1 to N-1.
ḟ reverse filter: remove all the elements from that range that are members of...
IA$ the increment list: get all the increments, take their absolute values (expressed as one monad via '$').
ɠḲVÇ“¡KṀȥƘạ»“¢⁼D»L? i/o main function:
ɠḲV read a line from stdin, split it on spaces and have Python parse each number (handling negative signs)
Ç ? run the above, and use the result on the following conditional:
L? if the length of the result is truthy (non-empty):
“¡KṀȥƘạ» then, return Jelly compressed string "Not jolly",
“¢⁼D» else, return Jelly compressed string "Jolly".
