I just checked and there’s no mistake.
Try to find the error in your solution.

yes my mistake ))) now all good )))
finally passed. Damn this took a while! I got to the unoptimized version pretty quick, but finding the faster one was tricky!
Anyone can please guide me how to optimize solution to this puzzle?
Hi, I optimized my solution, I’m stuck at validator 4 tho. I passed all the tests, so dunno where’s the problem. I’ll be looking into this more, but do you know what might be a case? @java_coffee_cup
Validator 4 is similar to its related test case. Both are randomly generated within a similar range.
If your code fails by error (not time out) I cannot exactly tell what can cause your code to fail.
Possible causes of error is overflow of integer and precision error if you use float-point numbers (js tends to use float-point even for integers)
You can generate your own input data and your calculated answer to post here. It is useful to others for debugging, and people can also help to cross check the correctness of your in-outs.
Hi, so as you suggested, I’ve generated 100 inputs and provided 100 outputs respectively. I set the starting value to be in range (3934, 91627) and the ending value to be from range (2025236, 4075607). Just some numbers from test 4 that seems kinda OK.
My solution is written in Python, so overflow of integer should not be a case. BTW I rewrited it in C++ and it keeps getting stucked at validator 4. I thought it might be something about precision, truncating numbers etc. so I’d be very glad if someone will compare my outputs to their.

Would you split the input and output into two blocks so that allowing direct copy and paste without further editing?

My program says:
Different outputs: 0
PS added input number in one of previous posts for future generations 
Do validator 4 have some output before truncating with decimal part of the number bigger than 999_999_999_999_999_8?
EDIT: actually the problem occurs when decimal part forms a string : ‘9999999999999999…’
Because I tested it in Python and after this point int() or floor() actually returns ceil. And casting to string also returns ceiled number. I didn’t figured out the way around that yet - if that’s a case ofc.
I do not work in python and have no idea why a decimal point is needed in integer calculation. If you could create a test triggering this mishaps situation I am glad to add it to a test case.
