The ^ operator in the PHP language is often used for encryption operations, and the decryption can also be done directly using ^, but when communicating with other languages, other languages such as objective-c may not be able to parse PHP's ^,
It is a binary-based bitwise operation that is expressed by the symbol XOR or ^.AlgorithmIt is the binary bit of the number on both sides of the operator. Take 0 for the same value and 1 for the same value. It differs from a Boolean operation in
Exclusive or operation for encryption and decryption
In an exclusive or operation, if a character (or value) x and a value m perform an exclusive or operation to obtain y, then use y and m to perform an exclusive or operation to restore x,

Turning a string over, for example, "12345" into "54321", is the simplest coding task. Even beginners of C language can
Use an exclusive OR operator to encrypt integers.I. What is the operator:
Binary ^ operators are predefined for integer and bool types. For an integer, ^ returns the bitwise XOR of the calculated operand ". For the bool operand, the logic of the ^
In this article, we will use the C language to implement the function of exchanging two variables of any type. It is difficult to use C for any type. If it is C ++, we can easily use the template function:
template inline void swap(T& t1, T& t2)
The problem of exclusive or operation on bytes after phpmd5 is encrypted $ string = "! & 22E2 &! '& 5aSJ ^ # $ & 6 $ Md5 = md5 ("0e2c83d839c026a5e05303167feb90". md5 ($ string, true), true );

Description
Given a weighted tree with N points, The subscripts start from 1 to n. Find two nodes in the tree and find the longest exclusive or path.
An exclusive or path refers to the exclusive or of all edge weights in a unique path between two
String encryption and decryption should be frequently used in data processing, but MD5 encryption is irreversible. Therefore, you can write an encryption and decryption function by yourself. I read a few different or implementation ideas on the
Conversion from: c |, |, &, &, Or ,~ ,! Operation
Bitwise operation
The bitwise operation component can only be integer or numeric type data. bitwise operations regard the operation object as Bit String information consisting of binary digits to
"^" Is an exclusive OR operator in C #. It can be understood as an exclusive operation.
The calculation rules are as follows:
Bytes --------------------------------------------------------------------------------------------------
True ^ false
I wrote an article a few days ago to exchange two arbitrary types of variables using the exclusive or operation in the C language, which is based on the algorithm of using ^ to exchange two integers:
a ^= b;b ^= a;a ^= b;
If you understand this
Question: uva12316-exclusive-or (with permission and query set)
I P V indicates that the value of XP is v. Or I p q V represents x P ^ x I + 1 ^ x I + 2... ^ x ^ q = V; then, Q k P1 P2 p3... PK asks the difference or value of these
Question 1: exclusive or exchange of two numbers
Suppose X = 2; y = 3. Our goal is (no tooth decay !!) Exchange the values of X and Y;
Take advantage of exclusive or particularity: x ^ x = 0
That is, the two identical numbers are 0;
Solution:
Make
Public void setopen (Boolean open, Boolean animate) { If (isopen () ^ open) {// The same is false, true } Public Boolean isopen () { return mcontent. getvisibility () = visible; }
As shown in the code above. You need to implement setopen () //
