In this cryptarithm, each letter above the line represents a digit differing by 1 from the digit represented by the same letter below the line. For example, if A=3 above the line, then A=2 or A=4 below the line. All occurrences of a letter on the same side of a line represent the same digit. It is also known that there are total of five digits in the solution.

 ADABA
+CACBA
------
 DBABC

the following combination works!

   56505

 +15105

-------------

71610

in such a case the no. of diffierent digits(0,1,5,6,7) used is 5.
