Help me in version control

enter code here
#include<stdio.h>
int main()
{
int t,i,n,m,k,l,o,j;
scanf("%d",&t);
while(t–)
{
scanf("%d %d %d",&n,&m,&k);int x[m],y[k],c1=0,c2=n;
for(i=0;i<m;i++)
{
scanf("%d",&x[i]);
}
for(i=0;i<k;i++)
{
scanf("%d",&y[i]);
}
if(m<k)
{
l=m;o=k;
}
else
{ l=k;o=m;}
for(i=0;i<n;i++)
{
for(j=0;j<o;j++)
{
if(x[i]==y[j])
{
c1++;break;
}

	    }
	    for(j=0;j<o;j++)
	    {
	    	if(i+1==x[j] || i+1==y[j])
	    	{
	    		c2--;break;
			}
		}
	}
	printf("%d %d\n",c1,c2);    
      }
        }

I am getting the correct output for the question Version Control System but the judge is giving me a Wrong Answer.Please correct me where im wrong.Thanks a lot in advance.

I am not quite getting what you are doing here. BTW, for me your code is giving 5 1 for first test case in sample example while output should be 4 1. Btw, Here is part of logic what wrote during contest that day, Full code can be found here,

as N is very small here, <= 100. so I just made an array with all 0’s initially…

int ar[n];
for(int i=0; i less than n; i++){
    ar[i]=0;
}

then marked 1 to all those elements which are 1 in first array.

for(int i = 0; i less than m; i++) {
    int data;
    cin  data;
    ar[data-1]=1;
}

And then just iterate through second array and checked which elements are in second array is marked 1, will be part of first answer. And marked these elements 1 too to find second answer.

int ans1=0;
for(int i=0; i less than k; i++){
    int data;
    cin data;
    if(ar[data-1]==1){
        ans1+=1;
    }
    ar[data-1]=1;
}

Now to find second answer I just iterated through marking array again and checked number of elements which are still all 0, to find second answer.

int ans2=0;
for(int i=0;i less than n;i++){
    if(ar[i]==0){
        ans2+=1;
    }
}

print ans1, ans2

Hope this will help.

Thank you so much.I really appreciate the help.Could you please tell me where i went wrong in my attempt?
Also,i updated my code and am getting outputs ‘4 1’ and ‘1 1’ as in the example.However,the judge still gives me a Wrong Answer.
