You're able to call numbers like 1-800-flowers which replace the characters with the associated numbers on a cellular device keyboard.
Conversion
abc = 2
def = 3
ghi = 4
jkl = 5
mno = 6
pqrs = 7
tuv = 8
wxyz = 9
This is your task:
- Create a function that takes a string as argument.
- Convert all letters to numbers by using a cellular device keyboard as reference and leave any other characters in.
- Return a string containing the argument with replaced letters.
Examples
dial("1-800-HOTLINEBLING") ➞ "1-800-468546325464"
dial("abc-def-ghi-jkl!!") ➞ "222-333-444-555!!"
dial("adgjmptw :)") ➞ "23456789 :)"
Notes
- While when you would write a SMS back in the day, to enter "b", you would have to press "2" twice. When calling numbers this is not the case as the range a-c gets converted to "2".
- Given string can contain upper and lowercase letters.
- Enjoy and good luck!
