My programme as follows

#include<stdio.h>
#define N 32767
#define M 10000
main()
{
char a[32770];
int state,data;
long n,k;
state=0;
for(k=0;k<=N;k++)
    a[k]=0;
    scanf("%ld",&n);
for(k=0;k<n;k++)
    {
       scanf("%d",&data);
       if(data>=0&&a[data]!=1&&a[data]!=3)a[data]+=1;
       else if(data<0&&a[data]!=2&&a[data]!=3)a[-data-1]+=2;
     }
scanf("%ld",&n);
for(k=0;k<n;k++)
    {
       scanf("%d",&data);
       if(M-data>=0&&M-data<=N)
     {
       if(a[M-data]==1||a[M-data]==3)
        state=1;
      }
       else if(M-data<0&&M-data>=-N-1)
     {
       if(a[data-M-1]==2||a[data-M-1]==3)
        state=1;
     }
     }
if(state)printf("YES");
else printf("NO");
}

.....ZZZzzzz

each element of the lists lays in the range from -32768 to 32767.
I don't think your array A is large enough....

I still get crash

My pro as follows
#include<stdio.h>
#define N 32767
#define M 10000
main()
{
char a[60000];
int state,data;
long n,k;
state=0;
for(k=0;k<=40000;k++)
    a[k]=0;
    scanf("%ld",&n);
for(k=0;k<n;k++)
    {
       scanf("%d",&data);
       if(data>=0)
       {
     if(a[data]!=1&&a[data]!=3)
        a[data]+=1;
    }
       else {
      if(a[data]!=2&&a[data]!=3)
         a[-data-1]+=2;
        }
     }
scanf("%ld",&n);
for(k=0;k<n;k++)
    {
       scanf("%d",&data);
       if(M-data>=0&&M-data<=N)
     {
       if(a[M-data]==1||a[M-data]==3)
        state=1;
      }
       else if(M-data<0&&M-data>=-N-1)
     {
       if(a[data-M-1]==2||a[data-M-1]==3)
        state=1;
     }
     }
if(state)printf("YES");
else printf("NO");

}
