Good question. I do a lot of interview questions, and I still have no idea what that would be.

Problem: Implement level search (search level by level for a particular element) in a binary search tree)

EX:        1
          / \
         2   3
        / \ / \
       4  5 6  7

In the above tree level-0 --> 1
                  level-1 --> 2, 3
                  level-2 --> 4, 5, 6, 7


Solution:
// We need a Queue inorder to perform a  search level by level. This queue will maintain the elements for each level.

int find_num(Tree *T, Queue *Q, int n)
{
     if (Q.Empty() == true)
           return -1;

     int num = Q.Deque();
     if (num == n)
     {
        cout << "found the number " << n ;
        return 0;
     }

     if (T->left != null)
     {
           Q.Enqueue(T->left->data);
     }

     if (T->right != null)
     {
          Q.Enqueue(T->left->data);
     }

     if (T->left != null)
     {
         find_num(T->left, Q, n);
     }
     
     if ( T->right != null)
     {
        find_num(T->right, Q, n);
     }

}
