Corner Cases What if the binary tree is null? Return true in this case. How is the binary tree represented? We use the level order traversal sequence with a special symbol "#" denoting the null node. For Example: The sequence [1, 2, 3, #, #, 4] represents the following binary tree...
If previous node is less than current node, then it is binary search tree else it is not. Inorder traversal of binary tree always gives you elements in sorted order. Java program: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 public static boolean isBSTInOrder...
if x 和 if x is not None if not x 和 if x is None 以上两行的式子都不是等价的!!! 当把None赋予一个变量x时,x也许被赋值了,也许未被赋值! 接下来测试x是否被赋值成功。 当使用 if x is None的时候,操作符是is,用来检查x的id。None在python里是单例,当使用if x的时候,不同类型是有一些不...

3. all elements in tree are sorted that in-order traverse takes O(n) time. OK, let me make a summary. If you know how many data to maintain, and have enough space to store hash table and do not need data to be sorted, hash table is always good choice. Because, hash table provid...
