Karakter yang terisolasi adalah karakter (selain baris baru) yang tidak memiliki karakter yang berdekatan dengan tipe yang sama. Karakter yang berdekatan dapat ke kiri, kanan di atas atau di bawah, tetapi tidak diagonal. Misalnya dalam teks berikut Hini diisolasi:

Ybb
YH%
%%%%

Semua karakter lain tidak terisolasi karena masing-masing memiliki setidaknya satu karakter lain yang bertipe sama.

Tugas Anda adalah menulis program yang mengambil string sebagai input dan menentukan jumlah karakter yang terisolasi.

Mencetak gol

Jawaban Anda akan dicetak oleh dua metrik. Yang pertama adalah jumlah karakter yang terisolasi dalam program Anda. Anda harus berusaha meminimalkan ini. Yang kedua adalah jumlah byte dalam program Anda. Anda harus meminimalkan ini juga. Ukuran program akan bertindak sebagai pemutus dasi untuk kriteria pertama.

Aturan tambahan

• Anda harus mendukung input pada rentang ascii yang dapat dicetak ditambah karakter apa pun yang Anda gunakan dalam program Anda.

• Anda dapat mempertimbangkan jeda baris untuk menjadi karakter baris baru atau baris baru diikuti oleh umpan baris.

• Anda dapat mengambil input dalam format apa pun yang masuk akal. Ini termasuk daftar garis.

Ini adalah salah satu program 05AB1E paling jelek dan terpanjang yang pernah saya tulis ..>.> Tantangan ini sangat sulit di 05AB1E. Saya tidak ragu dalam pikiran byte-count setidaknya dapat dibelah dua atau bahkan tiga / empat kali lebih kecil dengan menggunakan pendekatan yang berbeda (atau bahkan dengan pendekatan yang sama), tetapi saya saat ini tidak melihat caranya. Saya hanya senang itu berfungsi sekarang .. Jika orang lain memposting jawaban 05AB1E jauh lebih pendek dengan beberapa trik pintar saya mungkin akan menghapus jawaban ini karena malu ... xD
