A code of a regular binary tree with n-nodes is formed by labeling the left branches by 0's and the right branches by 1's and then traversing these branches in pre-order. Root is always assumed to be on a left branch. Different order of traversals yield different codes. An efficient ...
Figure 1 (a) Decoding architecture as a binary tree; (b) Node v received/response information 1.2 Contributions This paper introduces a novel polar code construction method, referred to as "fast polar codes", to facilitate parallelized processing at an SC decoder. In contrast to some existing ...
In this paper, we focus on the design of binary constant weight codes that admit low-complexity encoding and decoding algorithms, and that have size $$M=2^
本题其实和Binary Tree Inorder Traversal比较类似的,只不过是相反的,本题不可以按照正常的顺序来做,因为左子树然后右子树是比较难以转换的,因此可以采用倒着来,即先当前节点,然后是其右子树,做法和之前的中序是一样的,只不过是相反的思路,最后遍历完,把链表list反转过来,代码如下: 1/**2* Definition for a ...
本题要求在常熟时间内完成next()操作,并且在tree的高度的空间复杂度。思路是和之前的Binary Tree Inorder Traverse一样的,采用前序遍历的思路,因为受到存储的限制,因此只有一次存储一个DFS,代码如下: 1/**2* Definition for binary tree3* public class TreeNode {4* int val;5* TreeNode left;6* TreeNode...

A trie (pronounced “try”, as in retrieval) is simply a tree-like data structure where each node in the tree can have 0 -> N leaves. The familiar binary tree, for example, is a trie which imposes the restriction that each node has at most 2 leaves (a left and right leaf). Prefi...
