As the question, I am engaged in a little mixed, who can be careful to talk about: 1, composer psr-0 and psr-4 In the difference; 2, psr-0 specifications and psr-4 specifications of the difference; 3. composer and php-fig. For example, I am a bit confused. Who can tell me carefully:

Title, I'm a little confused, who can say it carefully:

Init is one of the most indispensable programs in Linux system operation. Init process, which is a user-level process initiated by the kernel. The kernel will find it in several places in the past that used Init, and its correct location (for Linux systems) is/sbin/init. If the kernel cannot find Init, it will try to run/bin/sh, and if it fails, the boot of the system will fail.Linux 7 RunLevel (0: shutdown, shutdown mode,1: single-user mode,2: Multi-

Very often when we create some view dynamically, we need to determine the layout of the other view by obtaining their width and height, but OnCreate () gets the width and height of the view to get 0.view.getwidth () and View.getheight () is the root cause of 0 because the control hasn't finished drawing yet, you have to wait for the system to finish drawing the view before you can get it.

Timeout....And then the book said with a hash table to achieve, see some of the hash of the puzzle is too ingenious, learn a bit.There is the problem can be solved with two points, first calculate the A+b, and then enumerate C+d, and then two points to find the scope.Hash 63
This question is the same as the two-point question. It only divides numbers into two heaps and uses the binary sorting method. However, it must be understood that it is not a condition to be found, there may be only duplicates. Here is the focus. As I continue my second journey, my time is very complex and the efficiency is not very good. After reading other people's code, it seems that all of them use hash, And the next stop is hash.
