Yup, i got the same idea. But im not familiar w Java syntax. I'll keep practicing.

Kruto!!! 😎

I did the same! nice

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.

Thanks for your solution, i did the same way but with a hashmap at first, which cost me a lot more operations.
