Hello

Hello ganesh,

This is a cool and interesting problem!
I wrote some code and let it run for a few hours and it generated this sequence:

So the longest path I have found is 74 steps, and the smallest number I have found that achieved this is 103682. (If my code is right.)
Maybe we could add this sequence onto OEIS!

Also, I chose to not allow leading 0s.
