A Introduction to Idea algorithmIDEA (International Data encryption Alogrithm) was presented by Xuejialai and James L.massey of the Federal Institute of Technology in Zurich, Switzerland, in 1991. IDEA uses a 128-bit key, the entire algorithm and Des similar, but also divides the plaintext into a 64-specific data grouping, and then after several iterations and a transformation, to obtain 64 bits of ciphertext.idea is to map two 16-bit values to a 16-bit value, which are:The half-
Code:
Copy the Code code as follows:
$a = Array (' a ' = = ' A ', ' B ' = ' B ');$b = Array (' c ' = = ' C ', ' d ' = ' d ');$c = $a + $b;Print ('
'); Print_r ($c); Print ('
');?>
Results:
Copy the Code code as follows:
Array([A] = a[B] = b[C] = C[d] + D)
Note: The Plus and array_merge () functions are also different, that is, when merging arrays with a plus sign, if there is a key with the sam

Because Popo cannot be used in Linux, the simulation results with wine are too bad, and there are always errors and they are almost useless. Therefore, I finally decided to get a Windows on Linux, find a circle, and finally find a mini version of Win98 plus 2, only 70 m after installation, qemu runs stably. But it is also very troublesome to install it from the beginning. The Win98
The current project uses the clickonce technology to deploy the client. The client sometimes needs to transmit some parameters from the server, for programs deployed in clickonce, we can use query strings in the launch URL to achieve this goal. Refer to the article on msdn and soon the code is finished. Okay. Try it. Deployment, from the launch client of the server, everything seems to be normal, and the value of all parameters has been successful.

These days, when HP acquired H3C, it was rare to see 3COM with 3 O-markers. But the problem, a year ago a project bought a 3COM switch 2924-SFP plus switch (PS: pure switch, no readable data). At that time saw a default management IP in the back, so log in to the Web interface configuration can be. Later the project bought H3C S5500 switch, do not have this switch, so idle.Due to the recent equipment is more tense, need to enable, the problem came, bu

I want to output $a = 1 on the screen, so I wrote the following, but only the last one is right.
There are two points to ask,
1th is the first two why only output the number, the front of the "$a =" and "$a =" is how to deal with it?
2nd, what exactly does the plus sign and dot number represent in PHP? Why didn't the two front signs have an error?

What is a lambda?lambda定义匿名函数,并不会带来程序运行效率的提高,只会使代码更简洁。为了减少单行函数的定义而存在的。lambda的使用大量简化了代码,使代码简练清晰。但是值得注意的是,这会在一定程度上降低代码的可读性。如果不是非常熟悉Python的人也许会对此很难理解。如果可以使用for...in...if来完成的,坚决不用lambda。如果使用lambda,lambda内不要包含循环,如果有,宁愿定义函数来完成,使代码获得可重用性和更好的可读性。如果你对你就喜欢用lambda来做,那也无可厚非,但是有内置函数减弱了代码的可读性!好了介绍完成了lambda,那就让我们来实际用一下,实例如下:Let's take a look at the combination of millet plus rifles.1.
