Explain me please, how to solve this problem without Memory Limit
Exceeded!

use the link stack link that:
typedef
  struct link
  {
     long d[10];
     next *link;
   }LINK;

instead of the structure of one data with one pointer, and you will
not get Memory Limit exceeded.

 typedef
   struct link
   {
      long d[10];
      next *link;    //This line should be 'link *next;'
    }LINK;
