Binary Tree zigzag level order traversal Given a binary tree, returnZigzag level orderTraversal of its nodes 'values. (ie, from left to right, then right to left for the next level and alternate ). For example: given binary tree{3, 9, 20, #, #, 15, 7}, 3/9 20/15 7 Return its zigzag level order traversal: [[3], [20, 9], [15, 7] Idea: Use two queues (one can
MySQL Binary log is often said to Bin-log, is the MySQL implementation of changes generated by the binary log file, its main role is two:* Data reply* Master-slave database. For the slave end to perform additions and deletions, keep sync with master. 1. Turn on binary log function Need to modify the MySQL configuration file, the experimental environment of this
problem Description: There are 10 kinds of people in the world, one understands the binary system, one does not understand. So you know the binary expression of two int32 integers m and n, how many bits are different? function Prototypes: int countbitdiff (int m, int n) Input: 1999 2299 Output: 7 Analysis: This topic from the 2016 Millet online pen test, to compare the bits of M and N, you can use the addit

Rotate the 90-degree output binary tree counterclockwise (Data Structure Test 2) and the 90-degree Binary Tree Rotating a 90-degree print binary tree in a counter-clockwise manner is a special medium-order traversal algorithm. Rotate 90 degrees counter-clockwise The implementation is also very simple, similar to the middle-order traversal algorithm. Before t

Yan Weimin's statement in this textbook: a binary tree with a depth of K and a number of nodes of 2 ^ k-1 is a full binary tree. This concept is well understood, It is a tree with a depth of K and no space available. First, number the full binary tree in the order of breadth first traversal (from left to right. A k-tree with N nodes in depth also numbers the tree

Analysis of conversion from negative to binary in JAVA, conversion from negative to binary in java I recently looked at the collection source code and found that ArrayDeque uses a large number of Operations, which involves binary. I suddenly found that I had a bit fuzzy on the negative binary number and provided some
Java implements binary tree and related traversal methods, and java implements Binary TreeImplement binary tree and related traversal methods in Java In computer science, a binary tree is a tree structure with a maximum of two Subtrees on each node. Generally, a subtree is called "left subtree" and "right subtree ).
Improvement of binary search-difference value search and binary improvement-difference value Difference value search In binary search, we can exclude half of the data volume for each comparison, which is highly efficient. If you use the keyword information, the amount of data excluded each time depends on the size of the keyword, the search will be more efficient
