Pick a four digit number, all digits different, such that when you add its reverse and divide it by 10, you get the number you started with.

For example: 1749+9471=11220, 11220/10 = 1122. Since 1749 is not equal to 1122, this is not the right number.

(In reply to Non-algorithmic solution by TomM)

I agree with what you said TomM, and this goes for Four Digit Number as well. I think my solution is like yours, (except more "pictures" and less words)

Should the solution be released for this problem?
