Hi everybody!!!
I'm getting RTE in this problem, and I don't know why. Somebody could help me?

Here is my code in Java:

Code: Select all

AC

Thanks in advance.

At the end of the input you're getting a java.lang.NullPointerException by calling trim() on a null String.

Hi brianfry713!
I have done changes you said me, but now I'm getting WA, what's wrong?

Code: Select all

AC

Thanks in advance again.

You have to stop the output when the input is a palindrome prime number (after outputting its double also).

You are comparing a StringBuilder to a String, which will always return false.

Thank you brianfry713!!! I got AC.
A very silly mistake comparing a String and a StringBuilder.
