Is there anyone kind enough to tell what's wrong with my Java code?

Question

I think I failed at splitting input into an array.. but I can't find what's wrong with my code. I already solved Balconies and Ballpark orders with split, so I just applied the same split code in this case, too.
I'll appreciate any comments!!

Answer 1

Instead of input.next() try:
input.nextLine();

Answer 2

And you should move the final if statement after the for loop

Answer 3

thank you so much!!! I changed input.next() into input.nextLine() and moved if statement and then it worked!!!
