I have multiplied two 3-digit numbers and coded the whole process twice:
In the 1st coding
replaces an odd digit and E
In the 2nd coding S
replaces a digit smaller than 6 and B
a digit bigger than 5.
Try to get my original numbers(digit 9 does not appear in the multiplication) and all other possible solutions, if any.

I hope I didn't offend. It's a fine problem, Ady. Thanks. I was just afraid that people might have been afraid to tackle it on account of the rating, and I wanted to encourage others to tackle it.
