Have you ever wondered why they always have alphabet next to the digits on the keys? Historically, have been used, mainly in the United States, as a technique for remembering telephone numbers easily. For example, an interior decorator might license the telephone number 1-800-724-6837, but advertise it as the more memorable phone word 1-800-PAINTER. Notice how there's an hyphen after every 3 digits. Q) How? A) When you type PAINTER you will actually end up typing on the keys 724-683-7 Write a program, which accepts a code word of the format '1-800-HOLIDAY and converts that into the original phone number. Example 1: Input: 1-800-HOLIDAY Output: 1-800-405-432-9 Example 2: Input: 1-800-BHANUPIZZA Output: 1-800-242-687-499-2 Hint: 1) Ignore the 1-800-part and focus on the alphabetic string part. 2) For every character figure out the digit of the key it belongs to.

Always assume the strings are not longer than 20 characters.
