# Password

The voltage station is every day changing the master password, which consists of three letters. Code generation process does not change and is based on the following procedure: The following letters (A) to (I) correspond to different numbers from 1 to 9. If we replace the letters numerals applied by the following sum.

HIG + CAB = EDF

If we letters change order, we would get the following sum:

CIH + EDF = GBA

Today's word slogan (password) is BEA, whatever means anything. Your task is to assign individual letters and numbers on this basis, to determine what number of password hiding themselves.

Tip on how to deal with: Use logical relationships and constraints arising from the submission and validity of the above totals, gradually exclude inappropriate combinations of numbers.
