the fast pointer to find the midpoint of the list, the left half of the list ends point to null, and recursively constructs a left subtree. The right half of the part is built recursively into the right sub-tree. If you do not want to destroy the original linked list, then you can use the first to save to the array and then build the method.1 PublicTreeNode Sortedlisttobst (ListNode head) {2 if(head==NULL)3 return NULL;4

1. Retrieve the first node in the first order.(The node in the first order is the root node.)2.The first node can be used to divide the middle order into left and right Subtrees, and then the second node in the first order can be used to divide the Left and Right Subtrees again,3. It ends when all the vertices are divided into single points.For example, assume that the first sequence of a binary tree is eba

the tree, as described in the background knowledge of Linux file management. In UNIX file systems, each file (the folder is also a file) can be viewed as a node. Non-folder files are stored on leaf nodes. The folder has pointers to the parent and child nodes (in Unix, the folder also contains a pointer to itself, which differs from the tree we see above). In Git, there is a similar
