Inconsistency in Codechef Judge

general
1

Hello coders,

I sometimes feel that there is inconsistency in the reported time taken by Codechef judge and Online IDE.
Please see my two submissions:

  1. https://www.codechef.com/viewsolution/19031855
  2. https://www.codechef.com/viewsolution/19027493

Both submissions are exactly same and still one is TLE and other is AC for subtask #1.

Considering that test cases may be randomly generated, many times when I test my code on online IDE, I find my verdict: Time Limit Exceeded(5 Sec). but, when I resubmit exact same code it shows code executed in 0.02 Sec.

Can someone explain what I am missing?

They are not same…

One has ,

int l,r

#another has,

long int l,r

And you are comparing “int” to “long int” in the solution u got TLE…(i.e in condition of “for” loop because “i,j” are long int and “l,r” are int)

Also, In CPP, it typecast accordingly. The problem arises if either of two value is above the range which was not the case here. Peace.

@admin you might wanna look into it!

If I am looking into it, it means that there is a high chance that I will drag @admin as well xD

Forwarded the case to them already, and they are looking over it.

Most probably it is a judge issue. The issue was fixed a few months ago and they are contemplating on why this occurred. But nothing I said above is concrete- they are still looking over it - so it might not be the actual reason.

I’d automatically update if I receive any follow up from them dear. :slight_smile:
