It is frustrating having to submit a perfectly good working code and the so-called computer tells you that the output is wrong. There needs to be a new level of constructive criticism that goes into the feedback for submissions. Feedback that actually tells you what is wrong and not just that it is not working! That is totally useless information to me. What am I supposed to do with code that is not working when I don't know what is not working?? Another level of this nonsense is when you submit and your answer it is correct when you test it on your computer, but when the checker checks it using a different operating system, and it doesn't compile correctly, instead of telling you to use a different syntax in your coding to match the allowed syntax for the OS the checker is using, oh no, it tells you ..."Compile error!". Wtf?!?
A new one I encountered today which is actually what made me write this blog is when your answer matches the answer required AND the checker shows the output and you have exactly the same thing as the answer it was looking for! But it says incorrect!?!?
Anyone who reads, please pass it on to someone who can help me fix this. I am still new here, so I don't really know where to submit bugs yet.
So, what kind of constructive feedback do you want? Line 37 is wrong? You used incorrect algorithm? It does give you the beginning of input/output/answer and you said it right — "That is totally useless information to me". The key part is "to me". You have to learn how to use this information to correct yourself.
I'm sorry, it's your problem. If you don't want this to happen — either fix some compiler/OS dependent issues or use the same compilers as on the server. The list is available here.
Again, I'm sorry, where did you find a bug? In each of your WA1 submissions, the lines clearly differ as the checker tells you.
Wait, so you looked at the answer I have and the answer expected and you saw a difference? Can you please show/tell me what the difference is? That really is my frustration. I can't see the difference.
When I saw this example, I didn't see symbol between BC and 23 in browser. I have seen that only after copying this to text editor. See my comment below.
Oh, I see. Out of 5 major browsers (IE, Firefox, Chrome, Opera, Safari) only Opera displays that symbol. I'm happy with my choice of browser. :)
About difference between: "BC23" and "BC23". I copied your answer to GVIM and found that there is "^V"(with ASCII code 22(0x16)) symbol between "BC and "23" in your answer. This symbol is hidden in standard mode.
