These two weeks are reviewing and examination, the progress is much slower. (The exam also felt that it was not ideal)Yao always wants us to write a program to deal with the class problem in the school. And then we're going to open the brain hole to design a. Writing applications should be time-burning, right?Next get the suffix array, and then there are DP, various sub-rule, MO Team, fight for Gdkoi before doing well?Also want to learn rausen to engage in pits plan, but think now is learning is

Title Description:Given a binary tree, determine if it is height-balanced.For this problem, a height-balanced binary tree was defined as a binary tree in which the depth of the Every node never differ by more than 1.Problem Solving Ideas:Recursive method to solve problems.The code is as follows:/** * Definition for a binary tree node. * public class TreeNode {* int val, * TreeNode left, * TreeNode right; * TreeNode (int x) {val = x;} *} */public class Solution {public Boolean

Test instructions: Look at the output to understand, violent enumeration, the maximum length of the string is 8, all lengths equal to 8 of the length is 8!=1x2x3x4x5x6x7x8=40320, the amount of data is smaller. Just the direction of the enumeration is rather weird, as in the case of a string of length equal to 3AAb,baAbc,acb,cabBac,bca,cbaBut the output is really not good output, in fact the output location is available to calculate.Solution:Make up a multi-fork tree, the root node is a, then the

Title:Given a matrix of m x n elements (m rows, n columns), return all elements of the Matri X in Spiral Order.For example,Given the following matrix:[[1, 2, 3], [4, 5, 6], [7, 8, 9]]You should return [1,2,3,6,9,8,7,4,5] . idea: Let's draw a spiral of our own walking trajectory. We will find that the helix always repeats four traversal processes, traversing to the right (column increments)--and traversing down (row increments) --> to the Left (column decrement) -->-up traversal (row decrement)

element continues to compare to the left Another thing is that because the array will change content after it is passed to the function, a new array B is constructed before each function, and the contents of the a array are copied and then output. Otherwise, do not use B array, directly pass a array, for two elements no problem, for three elements, in the IF aLocally modified several times, once AC, get the highest current of all topics ranked 74, before preferably 11234 row 79. is to do too sl

Received a new hospital website in August and took a look at it and felt it was unprofessional. Page layout is unreasonable, classification is also very messy, included only 110, IP is zero, the site is said to have thousands after the 3 team to do, did not do it, was become the group's most difficult to chew the bones, after knowing these circumstances, Oneself also some pressure, but by virtue of these years solid basic skills, to fix this site or n

The actual result is to find a full arrangement, because the maximum number given is 8, so there is a maximum of 8! . Based on the given example, we can regard it as inserting a new element into the inverted structure of the given arrangement (in
