PrefaceThe problem of string arrangement and combination has plagued me for a long time. I must master the recursive idea today. I will not talk much about it. I will start my blog! ProblemEnter a string to print all characters in the string. For

Due to the instability of fast sorting, the best time complexity is o (nlogn), and the worst can reach o (n ^ 2). To reduce the probability of occurrence of the worst case, you can use the schedood algorithm to improve it ~ [Cpp] include # Include #

/* Conclusion:The existence of vector frees developers from having to worry about memory application and release. However, the memory allocated behind the vector is allocated in multiples of 2. When the current capacity is insufficient for the

The difference between a directed graph and an undirected graph is a code difference. You can just comment out the code in the undirected graph. The difference between a directed graph and a directed network, that is, the difference in the weight

Problem DescriptionIf you ever tried to read a html document on a Macintosh, you know how hard it is if no Netscape is installed.Now, who can forget to install a HTML browser? This is very easy because most of the times you don't need one on a MAC

Question: There are N dice, and each dice has K faces, respectively marked 1 ~ K. Set the value of each dice to fi. If sum (fi) is equal to S, get a score sco = mult (fi ). Sum (fi) = f1 + f2 +... + fn Mul (fi) = f1 * f2 *... * fn   Calculate the

Analysis: A typical dictionary tree only adds a pointer for storing strings... Note the format output...     [Cpp] # include "stdio. h"# Include "string. h"# Include "stdlib. h"Struct tree{Struct tree * child [26];Char * str;};Struct tree *

Greedy algorithms always make the best choice for the moment. That is to say, the greedy algorithm does not take the overall optimization into consideration. All it makes is a local optimal choice in a certain sense. [Cpp]# Include # Define M

I did this question once before. I didn't want to understand it at the time, wa. I saw it again today. After reviewing the question, I confirmed that this was the largest ascending subsequence. At that time, I was very excited, however, I don't know

During the course of reading today, I learned another sorting method. It is similar to the sorting method. I have already written a method for selecting the sorting method. Here I will not explain too much about the sorting method. If you want to

I. general ConstantsThe declaration or definition format is as follows:Const = ; [1] const = ; [2]The definitions of [1] and [2] are completely equivalent.For example:Integer int (or other built-in types: float, double, char)Const int bufSize = 51

Function Requirement: input a string "1-2-3" to cut out "1", "2", and "3 ". Use the String split function in Java. The String in c ++ does not directly provide this function. You need to write it yourself.   The solution provided on the Internet is
