I recently saw a batch of interview questions and was interested. I had to solve the problem and practice my thinking.
Everybody's Test 1: a person can take one, two, or three steps at a time. How many steps can this person take on N layers?
Idea: first establish a mathematical model, set up three steps to go I, two steps
Work before the burning of writing
It is also proposed that after the project is compiled successfully, we can not in the beginning to burn the program into FLASH permanently saved. We need a series of settings,
First of all, in the menu Tools drop-down menu must have the following picture of the line section of the option, otherwise the burning work is not done, then how to add this option. We need to install the latest burn-in plugin below. EXE "Step to implement.

Preface
In the previous projects, there were more or less components that needed to communicate with each other. For various reasons,The cost of event bus is higher than that of vuex, so vuex is selected for technology selection, but I don't know why,Some new people in the team began to retreat when they heard about vuex, because vuex was very difficult? Is it really difficult?Today, we use three simple steps to prove how simple vuex is.
This is pu

Article Title: five steps to deploy Linux in security mode. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
Channel, which means that the path or method is a guide or rule set for the desired result. Similar to other channels, security requires a structured and systematic method. At the same time, it should also be
Crowded how to calculate the Steps per Unit of the outbound step? This side of the Steps per Unit refers to the plastic pushing forward to 1mm, which steps into a few steps. According to this definition, the calculation method can be usedStep into one lap the required number of ste
This is a problem involving the calculation of the number of steps;For this problem, my usual practice is to add a variable to the DFS function, step;In this way, we can easily control and record ( the smallest ) steps when we carry out the deep search function recursion.Topic:
This has a maze, with 0~8 rows and 0~8 columns:
1,1,1,1,1,1,1,1,11,0,0,1,0,0,1,0,11,0,0,1,1,0,0,0,11,0,1,0,1,1,0,1,11,0,
chessboard of BFS to analyze the situation, the problem has been done for a long time--、、、、#include can be resolved with enumerations, as followsN=2*m This situation is directly (M+N)/3 steps.If NThen consider N>2*m, first of all (0,1) situation special treatment. Then we can jump to (m,n) with M step, then the original problem is converted to (0,0) to (0,n-2*m). When N-2*m is a multiple of 4 we can directly ( -1,2) This jump can arrive at (N-2*M)/2 steps
Three Steps AheadHave you ever wished so had three legs? Imagine how much faster you could run. Today We is going to look at three steps to migrating GPOs between domains or forests with PowerShell. Now it is fast!The problemEver wanted to copy all the your production Group Policy Objects (GPOs) into a lab for testing? Do you have to copy GPOs between domains or forests? Do you need to migrate them to anoth
Analysis:There are a total of 25 steps, each step has two kinds of steps, go first level, or go two level. In two cases: if the first time to walk two, then there are25-2=23 Ladder to go. And then ask for the remaining 23 steps to the total number of walking method. If the first step, then there are 25-1 = 24 stepsTo go, so the total number of

Tags: Android style blog HTTP using Java file data sp Scenarios where ndk is used: 1. Some methods are implemented using local code in C, C ++. Then, I want to call these methods in Java. At this time, we need to use JNI technology. Why is C and C ++ code used for implementation? The reason is: 1. some functions need to be implemented using third-party class libraries. Third-party class libraries are written in C or C ++. Only C or C ++ code can use this class library. So, It is implemente
