Binary Tree : It is a tree data structure in which each node has at most two children. As such there is no relation between a parent and its left and right descendants. Hence they are unordered. Binary Search Tree : These are ordered binary trees wit…

What is Binary Search Tree (BST) A binary tree in which for each node, value of all the nodes in left subtree is less or equal and value of all the nodes in right subtree is greater The idea: We can use set boundry for each node. We take C tree for e…

tree - list contents of directories in a tree-like format. 树状显示目录结构 常用格式: tree [option] [directory] 常用参数(option): -a:显示所有文件及目录 -d:只显示目录 -l:如遇到符号链接的目录,直接列出所指向的目录结构 -f:在每个文件前显示完整的路径 -L level:限制目录显示层级 -I:忽略目录下的文件夹或目录 [director]:tree 命令作用于哪个目录下,默认当前目录. 示…
