I submitted my first solution to SPOJ today. When I looked at the status table, the row was colored green, but the result column says ‘0 edit ideone it’, the time is 0.0 and the memory is 0k. There is no error given, it doesn’t say ‘wrong answer’, nothing. I’ve searched the forums and read the FAQ, but nothing explains what the contents of the result column means in this case. I assume it’s not a good thing, but I don’t even know where to start. When I ran the code in ideone using the sample input, I got the correct answer. The problem I’m working on is Minimum Spanning Tree. Thank you.
