http://www.lintcode.com/zh-cn/problem/inorder-successor-in-binary-search-tree/ Description: Given a binary search tree (See Definition) and a node in it, find the in-order successor of that node in the BST. Example: Given tree =[2,1]and node =1: 2 / 1 return node2. Given tree...
Verify Inorder Sequence in Binary Search Tree 判断array是否递增。 Verify Postorder Sequence in Binary Search Tree 判断postorder和上面判断preorder是一模一样的,最后一个是root,然后从头到尾扫,如果当前的值大于root,则判断左边和右边部分是否是BST, 并且判断右边所有的值都大于root。 1publicboolean verifyPostord...
1. So, given the tree and target node, to find its successor. Require knowledge how recurise call work, mainly it should reach the leaf node, then print it from bottom to top. For the node which has both right and left side, it visits left first, then itself, then right side. func...

We propose an efficient parallel algorithm to number the vertices in inorder on a binary search tree by using Euler tour technique. The proposed algorithm can be implemented in O(log N) time with O(N) processors in CREW PRAM, provided that the number of nodes In the tree is N.Masahiro ...
1 利用preorder的特性:遍历preorder,如果当前值小于栈顶值,说明该值是栈顶元素左子树的值,将其压入栈中,如果大于栈顶值,则说明某节点的左子树已经遍历结束,是某元素右子树的值,需pop() stack top的数,并用stack top的值更新lower_bound,且后面遍历的所有数都必须大于这个lower_bound,这个比较、弹出、更新lower...

Memory Usage: 23.1 MB, less than 12.42% of C++ online submissions for Verify Preorder Sequence in Binary Search Tree. 可以看到中间写起来非常麻烦,稍不小心就漏一个条件,链接里面的写法就比较简洁了。while循环得很注意各种边界条件,然后一个while循环里面不同步骤,得仔细看是否前面会影响后面的边界。所以还...
