Output limit
by Br. Anand Shenoi 19 Dec '15

19 Dec '15

Hi All, What is the difference between the output limit in the global settings and that in the problem wise setting? When we set the Output limit for a specific problem, it gives TLE. If the output limit for the same problem is not set, it never exits from the memory. the status shows "JUDGING". It means, the global output limit is not being considered by DOM. Can anyone help please?

Problem not exiting
by Br. Anand Shenoi 18 Dec '15

18 Dec '15

Hi Jaap. There is a situation. Suppose if a solution has been submitted, but that solutions is not even passing the first test case and the program doesn't terminate. Usually it should be taken care of by DOMjudge right? Why is it not giving Wrong Answer or TLE. Here is the code: #include <stdio.h> #include <math.h> long long int gcd(long long int a, long long int b) { // base case if (b==0) {return a;} else {return gcd(b,a % b);} } long long int PowerSet(int *set, int set_size) { long long int pow_set_size = pow(2, set_size); long long int counter, j; long long int first=0,result=1; long long int proresult=1; for(counter = 0; counter < pow_set_size; counter++) { for(j = 0; j < set_size; j++) { if(counter & (1<<j)) { if(first==0) { //printf("\nFIRST%dFIRST\n",set[j]); result=set[j]; } printf("%d ", set[j]); first++; result=gcd(result, set[j]); } } first=0;proresult=(proresult%1000000007*result%1000000007)%1000000007; printf(" GCD %lld",result);printf("\n"); } return proresult; } int main() { int t=0,T; scanf("%d",&T); while(t<T) { int n,i,a[100002]; long long int ans; scanf("%d",&n); for(i=0;i<n;i++) { scanf("%d",&a[i]); } ans=PowerSet(a, n); printf("%lld\n",ans%1000000007); t++; } return 0; }

Possible to show runtime errors to competitors?
by Matthew Fahrenbacher 18 Dec '15

18 Dec '15

Hi all - is there a way to make runtime errors visible to competitors? I'd like our competitors to see that they are getting exceptions (ArrayIndexOutOfBoundsException, etc) and at what line of code (for java). Is this something that can be enabled? Thanks, Matt Fahrenbacher Niles West High School Skokie, Illinois

Any way to resolve this error?

Time specific for a problem & Global time limit
by Br. Anand Shenoi 14 Dec '15

14 Dec '15

Guys, A doubt: There is a "time limit" for each problem. There is a "time limit overshoot" in Configuration Settings. Does it mean that if we set the "time limit overshoot" as more than the maximum time limit for one of the problems in the contest, it will affect the others with the lower time limit? For example: Contest 1 has 5 problems 4 problems have 1 sec time limit. Rest 4 has 4 sec time limit. And let us say one of the submissions for 1 sec problem set goes into infinite loop. Will the problem exit as per 1 sec time limit for that problem or will I wait for the 4 sec global "time limit overshoot"?
