My code must pass in all tests but it falls in 4

#include <iostream.h>

int main()
{
bool array[65536];
for (int i=0;i<65536;i++)
  array[i]=false;
int num;
int N1,N2;
cin>>N1;
for (int i=0;i<N1;i++)
{
cin>>num;
array[num+32768]=true;
}
cin>>N2;
bool found=false;
for (int i=0;i<N2;i++)
{
cin>>num;
if (!found)
found=array[42768-num];
}
cout<<((found)?("YES"):("NO"));
return 0;
}

........
bool array[165536];   //here zero by default
int main()
{
//for (int i=0;i<65536;i++)
//array[i]=false;
......

42768+32768>65536

do not declare array as local variables.
it can be cause of stack oferflow (crash)
