Pose and solve the crypt-arithmetic problem SEND + MORE = MONEY as a CSP. In a crypt-arithmetic problem, each letter represents a dif- ferent digit, the leftmost digit cannot be zero (because then it would not be there), and the sum must be correct considering each sequence of letters as a base ten numeral. In this example, you know that Y = ( D + E ) mod 10 and that E = ( N + R + (( D + E ) ÷ 10)) mod 10, and so on.
