How to get to Shantou central blood station in Jieyang

1. It's better to charge by yourself

2.

bus line: Metro Line 8 → Metro Line 3, the whole journey is about 9.4km

1. Take Metro Line 8 from Changgang, pass 4 stops, and reach Kecun station

2. Take Metro Line 3, pass 3 stops, and reach TIYU West Road Station

3. Walk about 620 meters to reach Guangzhou Tianhe Sports Center

3. Walk about 240 meters from Changgang road terminus to Baogang Avenue South Station, take bus 813 (12 stops) and get off at TIYU East Road station. Cross the road and walk about 120 meters to the right to Zhengjia square (East Gate)
walk about 180 meters from Changgang road terminus to entrance / exit C of Baogang Avenue station, take Metro Line 8 (take 5 stops) to Kecun station, then take Metro Line 3 (Panyu Square Tianhe passenger station) (take 4 stops) to exit a of Shipaiqiao station. Walk about 380 meters to Zhengjia square (East Gate)

4. Bus route: Metro Line 2 → 702 → Hua 8, the whole journey is about 35.8km
1. Take Metro Line 2 from Changgang, pass 9 stops, and reach Feifei Park Station
2. Walk about 770m to Baiyun District government affairs center station
3. Take 702, pass 6 stops, and reach new century square east station (or take Guangzhou Hua Peizheng College Guangyuan passenger station)
4. Take Hua 8, Take Changgang Metro Line 2 and get off at Sanyuanli station, exit C2
2. Walk to the north station, 470 meters
3. Take No. 703 and get off at jiuguoguang station (pass 26 stations)
4. Take Hua 8 and get off at the central station, (passing through 14 stations) network map This data comes from the network map, and the final result is subject to the latest data of the network map

5. Hash is hash, definition is% hash = (); Write like this.

hash is a key value pair (key = & gt; In basic applications, for example, if you write a program and provide a setting part, you can probably write as follows:
% config = (
& quot; Window width & quot=& gt; 500,
" Window height & quot=& gt; 300,
" Background color & quot=& gt; & quot; Black",< br /> " Word color & quot=& gt; & quot; White",< br />
);
when you come to OO programming in the future, the initial attribute of an object will often be defined in this way.

an example of a more complicated point is to use it with array, or with another hash... For example, if you want to design a student form, you can probably write it like this:
% class = (
1 = & gt; {# Student number 1

& quot; First name & quot=& gt; & quot; Chen Dawen;, Gender = & gt& quot; Male & quot< br />
｝,
2 => ｛ # Student number 2

& quot; First name & quot=& gt; & quot; Chen Xiaowen;, Gender = & gt& quot; Female & quot< br />
｝,
.....

;< br />print $class{2}{" First name & quot;}# Chen Xiaowen

6. Guangzhou east station to Baiyun Airport, take line 3 directly in Guangzhou east station
go to the sports center and take Line 1 directly at Guangzhou east station
line 3 and line 1 close at 10:30 from Monday to Friday. Saturday and Sunday will be extended by half an hour. Chinese new year will be extended to 12 o'clock

7. Because hash value is the result of irreversible algorithm, it is the method to verify the uniqueness of the file
because it is irreversible, you can't get the original information of the file according to the hash value, so you can't get any information of the original file according to it. Of course, the file size is the information you have provided
but as a reminder, you can use hash value and file size as keywords to try on omnipotent douniang to see if there are any results

8. Bus routes: Metro Line 2 → Metro Line 8 → Metro Line 3 → APM line, the whole journey is about 22.4km
1. Take Metro Line 2 from Guangzhou south station, pass 8 stations, and reach Changgang station
2. Take Metro Line 8, pass 4 stations, and reach Kecun station
3. Take Metro Line 3, pass 1 station, and reach chigangta station
4. Take APM line, pass 6 stations, Arrive at the South Station of the sports center
5. Walk about 140 meters to reach the network map of Tianhe Sports Center This data comes from the network map, and the final result is subject to the latest data of the network map

Hash value, also known as hash function, is a method to create a small digital "fingerprint" from any kind of data

hash function compresses the message or data into a summary to rece the amount of data and fix the format of data. This function scrambles the data to create a new fingerprint called hash value

The

hash value is usually represented by a short string of random letters and numbers. A good hash function has few hash conflicts in the input field. In hash table and data processing, it will be more difficult to find database records to distinguish data without suppressing conflicts

extended data:

Properties of hash value:

all hash functions have the following basic characteristics: if two hash values are different (according to the same function), then the original input of the two hash values is also different

this property is the deterministic result of hash function, which is called one-way hash function. On the other hand, the input and output of hash function are not the only corresponding relationship. If two hash values are the same, the two input values are likely to be the same

but it may be different. This situation is called "collision", which is usually two input values of different lengths, deliberately calculating the same output value

input some data to calculate the hash value, and then partially change the input value, a hash function with strong obfuscation will proce a completely different hash value

typical hash functions have very large domains, such as SHA-2, which can accept (2-1) / 8 byte strings. At the same time, hash function must have a limited range, such as a fixed length bit string

in some cases, hash functions can be designed to have the same size of the domain and the injectivity between the ranges. Hash function must be irreversible
