Quick Sort Thinking Analysis: Select a datum element, usually select the first element or the last element. With a scan, the pending sequence is divided into two parts, some smaller than the Datum element, and a portion greater than or equal to the datum element. At this point the datum element is in the cor

the two sentences are printed, not the finish loop. However, the value of the stop can be found to be true. The blogger uses tools to restore the program to assembly code Here only a part of the assembly code, the red part of the loop, you can clearly see only in the 0x0193bf9d to do the stop verification, and the red part does not take the value of the stop, so the infinite loop. This is the result of JVM optimizations. How to avoid it? As with the command rearrangement, use the volatile ke

In some applications we need to dynamically display data, such as current online numbers, current total transactions, current exchange rates, and so on, front-end pages need real-time refresh to get the latest data. This article will be combined with examples to introduce the use of jquery and PHP to achieve dynamic digital display effect. This example assumes a dynamic display on the page (no need to refresh the entire page, but only local refresh d

To see if LM is in the Cpuinfo, if LM indicates support for 64-bit, LM means long mode, and the specific commands are as follows: Cat/proc/cpuinfo | grep flags Check to see if LM characters are inside the output Or Cat/proc/cpuinfo | grep Flags | grep LM | Wc-l Output is greater than 0 to support 64-bit CAT grammatical structure; d
