Answer 1

It is a very common problem while taking input in Java. It's explained in this article
https://www.geeksforgeeks.org/why-is-scanner-skipping-nextline-after-use-of-other-next-functions/

As you'll see in the article, the solution is to do a blank `sc.nextLine();` after a sc.nextInt() and before another sc.nextLine(). So to fix your code, simply add a line
`sc.nextLine();`
as the first statement of the while loop

XXX Thank you very much. I was actually aware of this concept but I never had to face it in a loop. Thank you!
