@palash_mittal : The questions from previous contests are moved to “Practice” section once the contest is over . If it is an external contest it is moved to “Peer” section of “Practice Section” . Otherwise it is moved to “Easy” , “Medium” or “Hard” section of the “Practice” section . The “Submit” link on contest page is be disabled after the contest , but the “Submit” link will always be enabled in the “Practice” section .

@palash_mittal Yes, old contest problems are included in the practice section with same name.

For instance check following example :

Contest Problem Link: [http://www.codechef.com/MAY13/problems/CHALENGE][1]

Practice Problem Link: [http://www.codechef.com/problems/CHALENGE][2]

Just remove contest code (MAY13 in our case) from contest problem URL and you are done.

Hope it helps, Best Luck :slight_smile:

We move every problem in the practice section.

The URL for a problem in the contest is of the form:
www.codechef.com//problems/

You just need to remove the from the URL and you are good to go. The link of the problem in the practice section will be:
www.codechef.com/problems/

Let us know if you face more issues. You can also mail it to [email protected].

#include<stdio.h>
void main()
{
long int i,num,n,k;
int count=0;
scanf("%lu lu",&n,&k);
for(i=0;i<n;i++)
{
if(num%k==0)
{
count++;
}
}
printf("%d",count);
getch();
}

Earlier if we went to an old contest problem and clicked submit, we were redirected to the practice problem.
Now, the submit button isn’t available for old problem, which would be more convenient.

I tried removing the contest code from contest problem url.

It is working well for internal contests like cook-offs as well as old contests(when we had the submit button even after contest ended which redirected us to the submission of the problem in practice section).
But not in case of external contests(recent).

Example:

Contest Problem Link: https://www.codechef.com/ZCOPRAC/problems/ZCO14003
Practice Problem Link: https://www.codechef.com/problems/ZCO14003 (removing the contest code from the url)

Contest Problem Link: https://www.codechef.com/CDSK2015/problems/CSP4
Practice Problem Link: https://www.codechef.com/problems/CSP4 (removing the contest code from the url)
An error occurs:
Attention
Problem is not visible now. Please try again later.

This seems to be for all recent external contests(Since 28-10-2015) except “ICPC Preparatory Series” and “CodeMasters 1.0”.

All the previous questions are added in the Practice session once the cotest is over. You access them in that section!
