yes the while loop will break if the f0 is below or equal to 0 or if n becomes 0
or both so if the loop breaks by n becoming 0 then still the f0 is larger than 0 so true else if f0 becomes 0 or below the loop breaks and then if n is 0 returns true else false.

there is String.lines() for creating the stream since java 11

Why would anybody consider this a best practice? It's hard to read, way to complicated and not at all embracing the Kotlin language. This is Java style of the 90s...

I think this solution is harder to read than an inline if

Updated a fork to resolve description merge conflict

Merge conflict, update the description.

n=0??

i like this one :)

Did you post your comment on the wrong solution by accident? This solution is fine, one of the others has the problem you described.

oopsie
should be fixed by now - waiting for approval to my test cases updates

Made some updates on test cases for java solutions. Pls review :)

Approved

you have encountered problem that had been already resolved - you are mutating the original array. What it means is you are probably passing a reference to an object rather than creating new, or making a shallow copy rather than deep one.

Java translation kumited :)
