1. Random tests are already available in all languages.
2. Rounding not necessary; result should be correct within margin of 1e-2

Resolving.

Please see the issue above.

Approved.

Maybe a little bit similar... But this was the condition I was asked about during the technical interview, so I decided to add it. It is a bit similar in terms of the condition, but the logic of returning the result and finding it is slightly different

Added 100 random tests

Expanded the description with clearer examples

Specified in description two cases where the function returns -1: insufficient funds and exceeding the available days of vacation compared to rental days

Enhanced basic examples

Fixed issues causing false positive test results in certain programming languages (e.g., JavaScript)

Added logging of input data (m, k, cost) in case of test failure for better debugging

Also, invalid input is not specified to return -1. Insufficient availability is different from insufficient funds; it should be specified separately.

( eleven languages while in Beta ?!? )

Resolved in this fork

Fixed in Python

updated to F# 6.0 + NUnit, using tuples

added some time ago

funny how 4 others did it as well

Nice to hear, thank you!

I will write a usual review. the original translator is still around so I won't hijack the translation yet.

I can, later today or tomorrow.
The solution setup looks good, so if you approve and problems are found, tests could be improved without invalidating solutions.
After skimming briefly over the code of tests I did notice one or two WTFs, but nothing what couldn't be fixed after approval.
