Of course it's not. The description cleary said:

for the purpose of this kata: ...

The tests say it very clear. At some point you are returning "" which is of course not a valid shortened URL.

Added.

Duplicate issue. Issue not specfied properly.

I had a look. It still has the old snake_case name.

Did you fix the initial code yet?

It doesn't really matter. We can always resubmit with the new name. We're in beta, it happens.

@anomaly7 Okay No Problem Bro ...

• It's My Honor Solving my Humble Kata ..

• and Please could you modify the Python translation By Adding Random Test Cases as the Issue still un-Resolved , i'll be so pleased With that .. thanks in adavnce .. regards ... Zizou

Well.. No doubt Good points .. I've Tried to Modify the Testcases BUT Unfortunately each time i try to add a single test case and validate the solution , Displaying Invalid Solution Error Message.. I don't know why ?? awaiting for any suggestion .. thanks in advance ..

Remove the usability of ceil function to make others think more

That should be marked as a Suggestion an not an Issue. And now this Kata has a new Issue - the constraints (no using math/ceil) aren't even mentioned in the Kata Description :(

UPDATE: Description issue fixed

Good opinion .. but i think bro you just misplaced it .. it not an issue as it is not a problem concerning performance or test cases .. it could be a suggestion better .. thanks again ..

That's a good suggestion bro ... I'll edit it now .. and you catch the point of this kata .. Just thinking , and no to use built-in function .... thanks again ..
