pointer is introduced, so we have to deal with the empty list separately. When the first linked list is an empty list, that is, its head node is a null pointer, then it is merged with the second linked list, and the process of the idler merge is the second linked list. Similarly, when the head node of the second linked list is a null pointer, we combine it with the first linked list to get the first linked

10,5,7. Next we take the node with a value of 10 from the data container. Notice that the node value of 10 is 5, 7, the node is placed in the container first, and then the two nodes are removed first, this is what we usually say first in first out, so it is not difficult to see that this container should be a queue. Because nodes with a value of 5,7,9,11 have no child nodes, they can be printed in turn.By analyzing specific examples, we can find the rules for printing binary trees from top to b
