Q: How can I figure out what was wrong in challenge quiz questions?

It doesn't seem terribly valuable if you don't learn from your past mistakes. Please advise. Thanks!

@Ram it's answer should be 2016...let me explain u how , below is the code public class Program { public static void main(String[] args) { int m=10; int n=15; for(int i=1;i<=10;i++) m++; n++; System.out.print(m); System.out.print(n); } } as after for loop there is no braces so just the next statement after for loop will come under it initially m=10 inside loop... 1st iteration - i=1, m++=10++=10 2nd iteration - i=2 , m++=11++=11(since postfix so m got incremented by 1 after 1st iteration) . . . 10th iteration - i=10 , m++=19++=19 exit loop...m becomes 20 encounter n++=15++=15 now m=20 and n=16 hence the output is 2016

@Steven ATOW, there has been suggestions but still no official hint that the questions will be disclosed to public reference other than in the challenges, so the best way would be to refer back to the tutorials or to ask here. @Filip I am just responsible over the cookies =^=

@Luka Sadly I believe those small tricks were "fixed" by our devs in the latest update.

@Hatsy - Thanks. Are you speaking from experience or are you a SoloLearn admin? It's a little difficult to suggest memorizing each question

It isn't about cheating, and I do think the challenges are a good way to learn since it gives immediate feedback on unique questions. At a minimum, I think it would be useful to be able to access the questions you answered incorrectly, even if detailed explanations aren't given.
