"," string input error

"," input giving me trouble...

Straightforward..

Those 3 dots is where the answer is. The function accepts String arguments (args), any number of arguments.

Looks good. I used the if-else statements, the rest is the same. Thanks for the answer..

Interesting problem. Had to polish my skills on using args to tackle the problem.

A bit tricky but succeeded. The code is tighter than I anticipated.

I underestimated the challenge but after a several attempts solved it. Exciting..
