I decided to go the long way, and then saw this. Hurray, i learned somthing new

ahhaha, i spent about a 20 minutes for solution, and then a saw it.

instant facepalm when I saw this

10/10

how come, I didnt even know this method existed.

Lmao my jaw dropped when I saw this. Never knew this existed.

i also laughed when i saw this solution because i over complicated mine like maniac

Had no idea this existed! that's a clever and funny solution!

What would you return in case this situation happened?

I mean, my if statement involving Substring and stuff was not awfully messy and ran relatively fast but there was a function ready for that? Snap!

Nice, did not know this! Good to know!

Bro.. i used while loop and if-else for this @@. It took me so longgg

oh

No need, the numbers passed are assumedto be always positive
