The company took over the job of doing a travel website, using the traditional JSP and java, the front-end side can not do I used JQ plus underscore template, test a bug, ie11 access to a page can not open, read the following report underscore syntax error, line by lineTo see if there is a syntax problem in the template, it seems to look right, line by line deletion code to eliminate the problem, found the problem is，Change intoThat’s right. The question of annotation has to be Google’s strength. Write it down and leave it for yourself.
Checkpoint 1.1:
（1）1The addressing capacity of a CPU is 8KB, so the width of its address bus is13position
Because 8KB=8*1024B=2^13
（2）1KBThe memory has1024The number of storage units and the number of storage units.0reach1023
1KB=1024B，Numbering from 2^0 to 2^10-1
（3）1KB=1024B=1024*8bit
（4）1KB=2^10B 1MB=2^20B 1GB=2^30B
（5）8080,8088,80286,80386The width of the address bus is 16, 20, 24, and 32, and the data they can transmit at one time are:64KB,1MB,16MB,4GB
If a CPU has N address lines, you can say that the width of the CPU address bus is N, and you can f...

The problem is Union Find.
Is there any 3 elements that determine whether some sides are tree?
1. The number of edges is not the number of points -1?
2. Each side can not be joined by ring; (when adding edge to do check).
3. When all sides are joined, the edges must be connected; (all sides are added to see the number of Union).
First, define the class of UnionFind. Defining interface
class UnionFind{
int[] father;
int size;
public UnionFind(int size){
father = new int[size];
for(int i = 0 ; i < size; ++i){
father[i] = i;
}

Presumably all the CTF guys have touched the Android converse more or less, so Big Brother is going to give you a whole series of static and dynamic analysis of the Android converse. This installment begins with a static analysis of the Android reverse, including the use of reverse tools, file descriptions, example parsing, and so on..
AndroidReverse is the process of decompilation, because you do not understand the Android forward compiled results, so the premise of static analysis in CTF is to decompile the file appears to us to understand a layer of source code, static analysis.

1.When I did ajax, the data was sent successfully, and the background confirmed that the message was returned, but it couldn’t be received in success anyway. The reason I met was due to the wrong dataType return value type.
var url = "Request data interface / path ";$.ajax ({Method:'post',Async:false,DataTye:'json',Url:url,Success:function (data)) {Console.log ("return value" +data);}})
In the last section of Ajax sending, the background gave me a text-type data when I returned, but my dataType was written as json, causing how to print out the returned data, small details, can not be ...
