Reraised as issue

No random tests in Java

Thanks for the kata. Not to be too pedantic, but I'd suggest mentioning that the bounds are ordered and inclusive.

Thanks again.

While this can be done without using Strings at all, from looking at your code snippet I'd suggest you review your loop conditions.

Nothing is strinking any hint please

Haskell solution kumited and ready for take off.
Beware, a straight forward solution could have some server time problems ...
Kindly request te release it.
Suggestion #2 from Pyramidka included.
Demki's suggestion included as well.

Think of the solution where you don't have to use strings at all.
You have a number and you can use arithmetic operations to get its digits. That should be faster.

Make sure you exit any loops initialized

As I am running the code I am getting timeout issue as code is taking longer than 12000ms .Can some suggest me how to optimize the code.Plese be fast

There's a couple.

1. I'd like someone translate this kata to Python. I wish I could do it myself but have insufficient honor points.
2. It's possible to set ticket numbers range from 1 to 999,999. In that manner numbers would have more natural look and the kata would be a bit trickier.

Nice kata - if you like XOR katas, you can check mine -

I'd suggest some random tests
