Title: Leetcode 003 Longest Substring without repeating charactersTest instructions: Gives a string that finds the oldest string with no repeating characters.Example: "BBBBB" returns the length of "B" 1; "ABCABCBB" returns the length of "ABC" 3.Ideas:Dynamic planning. Dp[i] represents the longest length of a substring with no repeating character ending with an I-character, which requires a secondary array of idx[s[i]] to record the position of the las

[Python exercise question 003]An integer. After 100 is added, it is a full number of workers, and 168 is a full number of workers. What is this number?
-------------------------------------------------
The so-called "full number" means that the root number is still an integer.
The mathematical scum is like this: Assume that the number is less than

Today I will mainly review the data structure.Tree
Red/black tree (symmetric Binary Tree B) (wiki)
Features:
Advantages:
Purpose: used to construct correlated arrays (Map) and sets)
B tree
B + tree
Feature: No data is saved for each keyword and is only used for indexing. All data is saved on the leaf node. if the search is successful, the process ends only when the query is successful on the leaf node (different from B-tree)

First step: x = sqrt (i+100). if x = = Floor (x), It proves that X is an integer. The second step is
