It can be seen that the elements of the phase are located at a [4] and a [8], that is, the same elements can be found only when the array loops to a [8.Loop once:

Atomic variable analysis in Linux Kernel
There are several things in the Linux kernel that are common, and atomic variables are one of them. In fact, I have never tried these things before. After all, there are just a few lines of code, as long as I know what this means. It is limited to knowing that there is an assembly command called lock. This ensures the atomicity of data operations. But a few days ago, for some reason, I flipped through the RCU code. The RCU code was not locked when the poi

pointer operation has the addition and subtraction of pointers and numbers, subtraction of the same type of pointer, and if it points to the same number of groups, it does not make much sense. Similarly, pushing different types of pointers makes more sense and even makes an error.Here is an example of a pointer arithmetic that exchanges two variable values without taking advantage of additional variablesAfter all, the new keyword or application of additional memory, although no application vari
As described in the Android documentation, the SDK level (integer) of the phone is running are available in:
Android.os.Build.VERSION.SDK_INT;
The enum corresponding to this Int. Android.os.Build.VERSION_CODES class.
Code Example:
int currentapiversion=android.os.build.version.sdk_int;if (currentapiversion >= Android.os.Build.VERSION_CODES. FROYO) {
Do something
}else{
Do something
}
Note:
This sdk_int is available since donut (Android 1.6/api4)

Error object: ndbcntr (line: 273) 0x00000006
Cause Analysis: this problem occurs because the UNDO log file space is used up!
Solution: add the UNDO log space file. The syntax is as follows:
Alter logfile group lg_1
Add undofile 'undo _ 2. Log'
