you deserved a clever

Thats a bit overkill isnt it?

"." could be lifted out of ternary if :)

"You can use if..else or ternary operator to complete it."
Ok.

if someone new is having doubt here go read about String pool, basically in each concatenation a new string object is created and it consumes way too much memory

Ahuenno pocany

Any code monkey can do it the string way. We don't see many solutions that do it the math way. Good one!

you made me chuckle XD

lolololol

Because a String object can't be changed. In this code in the line "s+=string;" a new string is created every iteration.

syka blyat .. good one )) Prosto zaebis
