The need for B-tree arose with the rise in the need for lesser time inaccessing the physical storage medialike a hard disk. The secondary storage devices are slower with a larger capacity. There was a need for such types of data structures that minimize the disk accesses. Other data struct...

前序遍历(Pre-order Traversal):首先访问根节点,然后递归地前序遍历左子树,最后递归地前序遍历右子树。 中序遍历(In-order Traversal):首先递归地中序遍历左子树,然后访问根节点,最后递归地中序遍历右子树。 后序遍历(Post-order Traversal):首先递归地后序遍历左子树,然后递归地后序遍历右子树,最后访问根节点。
