Teks buku anak-anak Beruang Kutub, Beruang Kutub, Apa yang Kamu Dengar? memiliki pola yang sangat sederhana. Anda mungkin menggunakan teks untuk mengajarkan konsep pemrograman pengantar.

Anak saya cepat bosan dengan ide ini, jadi saya memutuskan untuk bermain golf dengannya.

Tantangan

Dalam bahasa pemrograman pilihan Anda, tulislah program sekecil mungkin yang akan mencetak teks berikut. Output harus sama persis, termasuk case, spasi, dan tanda baca.

Polar Bear, Polar Bear, what do you hear?
I hear a lion roaring in my ear.

Lion, Lion, what do you hear?
I hear a hippopotamus snorting in my ear.

Hippopotamus, Hippopotamus, what do you hear?
I hear a flamingo fluting in my ear.

Flamingo, Flamingo, what do you hear?
I hear a zebra braying in my ear.

Zebra, Zebra, what do you hear?
I hear a boa constrictor hissing in my ear.

Boa Constrictor, Boa Constrictor, what do you hear?
I hear an elephant trumpeting in my ear.

Elephant, Elephant, what do you hear?
I hear a leopard snarling in my ear.

Leopard, Leopard, what do you hear?
I hear a peacock yelping in my ear.

Peacock, Peacock, what do you hear?
I hear a walrus bellowing in my ear.

Walrus, Walrus, what do you hear?
I hear a zookeeper whistling in my ear.

Zookeeper, Zookeeper, what do you hear?
I hear children...

...growling like a polar bear,
roaring like a lion,
snorting like a hippopotamus,
fluting like a flamingo,
braying like a zebra,
hissing like a boa constrictor,
trumpeting like an elephant,
snarling like a leopard,
yelping like a peacock,
bellowing like a walrus...
that's what I hear.

‘€JU
Produk Cartesian dari daftar "Hewan, Hewan," dan "apa yang Anda dengar? \ N", diratakan dan bergabung dan simpan dalam variabel X. Pruduces daftar string dari bentuk "Hewan, Hewan, apa yang Anda dengar? N ".

¦“„¾“‚˜l
Ambil daftar hewan tersisa dari sebelumnya, keluarkan penjaga kebun binatang dan tambahkan anak-anak, konversi ke huruf kecil.

• beberapa pemberitahuan untuk konstanta yang tidak terdefinisi; PHP implisit dilemparkan ke string literal menendang lagi
• menambahkan "n" untuk "seekor gajah" memakan waktu 20 byte ... hmpf.

• Lebih merapikan dan menghapus subskrip yang dibuat berlebihan dengan memindahkan children, menyimpan lebih lanjut 27 byte.

• Ganti writeLinesdengan catdan diformat ulang dengan tepat (ditambahkan \ndi beberapa tempat) yang disimpan 3 byte

Karena %*Batch adalah hal yang terdekat dengan array. Jika saya dapat menggunakan Polar beardan Boa constrictorkemudian saya dapat menghemat 10% ... tapi saya masih lebih dari 50% dari teks asli ...

Sunting: Disimpan 3 byte dengan pengaturan e=echo(dengan (bukan spasi, yang memungkinkan saya untuk menggunakannya untuk menggemakan baris kosong, meskipun saya kemudian harus menulis @echo offsecara penuh.

Bash + zcat, 402 byte

Just a joke:
skrip bash 2 baris yang mengekor sendiri dan menyalurkan baris kedua ke zcat.
Baris kedua adalah teks yang di-gzip.

Cara mempersiapkannya: semua teks dalam file a. Kemudian

echo "tail -n+2 \$0|zcat;exit" > go.sh
gzip a ;
cat a.gz >> go.sh
chomod u+x go.sh

File yang dibuat saat dieksekusi mengembalikan teks awal, 402 Bytes.

F #, 591 589 579 576 573 567 552 byte

Ini adalah percobaan pertama saya di golf kode dengan bahasa yang saya suka. Saya yakin ada beberapa cara ini bisa dibuat lebih pendek. Berjalan di FSI, jadi tidak perlu .NET boilerplate.

Sunting: Dicukur 10 byte dengan menghapus \r. Itu masih membuat baik di VSCode jadi pergi mencari. Potong tiga byte lagi dengan komposisi fungsi, dan tiga byte lainnya dengan lambda, lalu enam dengan for loop, bukan Seq.iter (singkirkan lambda). Akhirnya 15 byte dipotong dengan mengatur ulanga(s:string)

let S="growl,roar,snort,flut,bray,hiss,trumpet,snarl,yelp,bellow,whistl".Split(',')
