Is this the code I'm going to see if I work as a software engineer in Japan? Hahaha

What kind of sorcery is this?

Thanks for sharing this advice. I was thinking this was a clean way of doing it.

s.charAt() will returns character type data so when you concate with "", it will become String type

one liners doesn't mean clean code

dude...

This so funny LMAO. I love how this guy made a one liner solution so freaking complicated

What the hell is this?! LMAO how's this a correct solution

(one of the trickiest too, actually....! x) )

Yup, it's one of the most powerful feature in programming. You won't regret learning it :)

I don't get it

I'm not that good in Java but just wanna know why you have to assign "" with s.charAt(i2)+s.charAt(1+i2)?

but what if the array isn't in reverse order?
