Diberikan dua input q n
menentukan apakah q
residu kuadratik n
.
Yaitu, adakah di x
mana x**2 == q (mod n)
atau q
mod persegi n
?
Memasukkan
Dua bilangan bulat q
dan n
, di mana q
dan n
adalah bilangan bulat apa pun 0 <= q < n
.
Keluaran
Kebenaran atau kebohongan.
Secara opsional, cetak semua (atau semua) x
yang adax**2 == q (mod n)
Contohnya
>>> quadratic_residue(1, 5)
True
>>> quadratic_residue(3, 8)
False
>>> quadratic_residue(15, 22)
True
Aturan
Kode Anda harus berupa program atau fungsi. Masukan bisa dalam urutan apa pun. Ini adalah kode golf, jadi kode terpendek dalam byte menang.
Jika ada yang tidak jelas atau perlu diperbaiki, beri tahu saya.
Bonus
- Bonus 2-byte jika fungsi Anda menerima
q
bilangan bulat sembarang.

q
dan n
menjadi dua bilangan bulat, tapi jadi saya tidak memecahkan jawaban yang ada,0 <= q < n
q
0 <= q < n
. Anda mungkin harus mengklarifikasi apakah asumsi ini dapat diterima atau tidak.
