Problem Statement:

When we share our phone numbers with others, we share the numbers digit by digit.

Given a phone number in words, convert the number to digits.
For example, convert “six four eight three” to “6483”.

1. All phone numbers will be 10 digits.
2. Two repeating digits will be shortened using the word “double”. Three repeating
   digits will be shortened using the word “triple”. If the digits repeat four or more
   times, they will be shortered using ‘double’ and ‘triple’ mutiple times.
