The product of 722*227 (163,894) contains neither 2 nor 7.
List all the couples (b,c; b>c) such that the product bcc*ccb contains neither b nor c.
Bonus: From the above list select couples, if any, using none of the corresponding digits in the partial products as well.
It's a pity, but I can't solve this problem yet, although have already completed half of the course on algorithms. I even made more than a million playing at
https://777spinslot.com/red-chilli-wins/ but this task is difficult for me. I hope that will solve it soon.
Who has any ideas?
