Problem B - Find the Telephone

Time Limit: 1 second

In some places is common to remember a phone number associating its digits to letters.In this way the expression MY LOVE means 69 5683. Of course there are someproblems, because some phone numbers can not form a word or a phrase and the digits1 and 0 are not associated to any letter.

Your task is to read an expression and find the corresponding phone number based onthe table below. An expression is composed by the capital letters (A-Z), hyphens (-) and the numbers 1 and 0.

Letters	Number
ABC	2
DEF	3
GHI	4
JKL	5
MNO	6
PQRS	7
TUV	8
WXYZ	9

Input

The input consists of a set of expressions. Each expression is in a line by itselfand has C characters, where 1 ≤ C ≤ 30. The input isterminated by enf of file (EOF).

Output

For each expression you should print the corresponding phone number.

Sample Input

1-HOME-SWEET-HOME
MY-MISERABLE-JOB

Sample Output

1-4663-79338-4663
69-647372253-562
