 * Beeswax
 * The word BEESWAX represents a number in a criminal's secret code,
 * but the police had no clue until they discovered among his papers the following sum:

E A S E B S B S X B P W W K S E T Q -- K P E P W E K K Q
 * The detectives assumed that it was an addition sum, and utterly failed to solve it.
 * Then one man hit on the brilliant idea that perhaps it was a case of subtraction.
 * This proved to be correct, and by substituting a different figure for each letter, so that it worked out correctly,
 * they obtained the secret code.


 * What number does BEESWAX represent?
