pengantar

Saya bisa mengetik dengan kecepatan sedang, menggunakan tata letak keyboard QWERTY. Tetapi jika sebuah kata seperti yellowwooddoor memiliki satu ton surat yang diulang, dibutuhkan waktu lebih lama untuk mengetiknya. Lebih buruk lagi adalah ketika kata seperti "lompat" memiliki jari yang sama digunakan untuk beberapa huruf berturut-turut yang berbeda.

Inilah waktu yang saya perlukan untuk mengetik huruf pada setiap jari (diukur sangat tidak ilmiah):

Kolom adalah Nama jari, penekanan tombol / detik, detik / penekanan tombol, dan tombol yang digunakan oleh setiap jari

Data yang sama dalam format CSV .

Dibutuhkan

.75 * (first_finger_same_letter_time + second_finger_same_letter_time) / 2

waktu untuk beralih di antara dua jari.

Tantangan

Diberikan string sebagai input, berapa lama untuk mengetiknya?

• "Timer" memulai saat tombol pertama ditekan dan berakhir ketika tombol terakhir ditekan. Anda hanya menghitung waktu antara penekanan tombol.
• Ini adalah kode-golf . Jawaban terpendek dalam byte menang.
• Pengajuan dapat berupa program atau fungsi yang lengkap.
• Input dan output dengan cara apa pun yang Anda inginkan , stdin / out, params fungsi, file, tidak masalah.
• Output harus akurat ke setidaknya 3 tempat desimal (+/- 0,001 untuk kesalahan pembulatan baik-baik saja). Leading 0. untuk angka di bawah 1 dan mengikuti baris baru opsional.
• Input akan berupa string yang berisi (huruf kecil) az, 0-9, spasi, titik koma, koma, titik, dan apostrof.
• Saya selalu mengetik spasi dengan ibu jari kanan saya.
• Saya menggunakan jari pengetikan sentuh normal (Anda juga dapat melihat tabel di atas untuk pemetaan tombol-jari).
• Kode referensi yang digunakan untuk menghasilkan kasus uji

Menyimpan penundaan

$g$$0\le x \le17$

g = x => 10 / Buffer('4.2.5-75E6?3>4=4AA')[x]

$x$

• dua kali nomor nampan untuk mendapatkan penundaan untuk surat yang sama
• dua kali angka bin +1 untuk mendapatkan penundaan untuk huruf yang berbeda
