A binary tree comprises of parent nodes, or leaves, each of which stores data and also links to up to two other child nodes (leaves) which are visualized spatially as below the first node with one placed to the left and with one placed to the right. Some of the important points of a...

Using a queue is the proper way to print data in a binary tree level by level as a stack is fordepth-firsttraversal. However, there’re three different ways to achieve this goal: writing your own algorithm using a queue (or linked list node) or using the Hashing technique. ...
Balanced Binary Tree (Easy) 平衡二叉树 题目: Given a binary tree, determine if it is height-balanced. 给定二叉树,确定它是否是高度平衡的。 For this problem, a height-balanced binary tree is defined as: 对于此问题,高度平衡二叉树定义为: a binary tree in which the depth of the......
树状数组(Binary Indexed Tree) 【引言】 在解题过程中,我们有时需要维护一个数组的前缀和S[i]=A[1]+A[2]+...+A[i]。 但是不难发现,如果我们修改了任意一个A[i],S[i]、S[i+1]...S[n]都会发生变化。 可以说,每次修改A[i]后,调整前缀和S[]在最坏情况下会需要O(n)的时间。

recursive binary tree Feb 6, 2012 at 11:45am swp(12) hey guys, ive got this binary tree program meant to just take in numbers, and output them inorder, but i cant seem to get the print function to work, everything compiles so im lost, a little help would be much appreciated!
