Can anyone explain how to generate all numbers efficiently in easy problem :)
It's easy to see that almost any answer has all digits in non decreasing order, therefore you can generate them storing current length and last digit.

250 can be solved by brute force searching < 1e7, if not found use oeis_seq (goal — base0)
Why aren't ratings being updated? The round was rated, right? hmehta?
Sorry, there was a slight delay coz of the Japan Regional Round Results to be published before this round but they were updated a day later :)
