Телефони и клавиатури

Представете си (не толкова) далечното минало. Няма "умни телефони", няма iPhone, но пък има ей такива клетъчни телефони:

motorolla nokia sony-ericsson lg

...и естествено, всеки ден си счупвате пръстите от писане на SMS-и.

Клавиатурите

Цифрови клавиатури ("във формата на шоколад") с 4 реда и 3 бутона на ред ("общо 12 блокчета шоколад... хммм... а сега ти се яде шоколад... изяж един шоколад... сега... но да е тъмен шоколад... по-полезен е..."):

------- ------- -------
|     | | ABC | | DEF |
|  1  | |  2  | |  3  |
------- ------- -------
------- ------- -------
| GHI | | JKL | | MNO |
|  4  | |  5  | |  6  |
------- ------- -------
------- ------- -------
|PQRS | | TUV | | WXYZ|
|  7  | |  8  | |  9  |
------- ------- -------
------- ------- -------
|     | |space| |     |
|  *  | |  0  | |  #  |
------- ------- -------

За да въведете символ (например буква от азбуката или запетая), натискате определна цифра няколко пъти. Това се нарича multi-tap въвеждане на текст.

Например, за да въведете буквата K, натискате бутона 5 два пъти (символите се въртят така J -> K -> L -> 5, което означава: едно натискане - J, две натискания - K, три натискания - L, четири натискания - 5).

Особености:

  • Бутон остава въведен, ако бъде натиснат друг бутон или след кратка пауза. Тоест не ни е нужно допълнително натискане, за да изберем буква.
  • Бутонът 1 въвежда единица (1) с едно натискане. Нищо повече. Ако натиснем бутонът n пъти, ще въведем n единици.
  • Бутонът 0 въвежда празно място или нула в реда space -> 0.
  • Бутоните * и # работят на принципа на бутона 1.

Следователно, за да се изпрати съобщението "WHERE DO U WANT 2 MEET L8R" са нужни 47 бутон-натискания.

Бутон-натискания

Бутон-натискане е термин, означаващ натискане на произволен бутон от клавиатурата на телефона.

В края на деня е жизненоважно да знаете колко бутон-натискания сте направили в писане на SMS-и!

Дефинирайте методът button_presses(message), който приема съобщение и връща броя бутон-натискания, необходими за изписване на съобщението.

Примери:

button_presses('nvm') # => 6
button_presses('WHERE DO U WANT 2 MEET L8R') # => 47

Забележки

  • space означава низ с празно място - ' '
  • Игнорираме пунктуацията (но само за целта на предизвикателството!)
  • Приемаме, че телефоните не правят разлика между главни/малки букви, но методът трябва да може да приема и главни, и малки букви

  • Ще ви гледаме много лошо до края на света, ако hardcode-нете броя на бутон-натисканията за всеки символ. Нещо подобно на:

    {'a' = 1, 'b' = 2, ..., 'o' = 3, ...}
