如果我们想查找这样的单词--它里面出现了字母q,但是q后面跟的不是字母u,我们可以尝试这样：
...

Cancel
\b\w*q(?!u)\w*\b。
...

Cancel
\b\w*q[^u]\w*\b匹配包含后面不是字母u的字母q的单词。但是如果多做测试(或者你思维足够敏锐，直接就观察出来了)，你会发现，如果q出现在单词的结尾的话，像Iraq,Benq，这个表达式就会出错

断言此位置的后面不能匹配表达式exp

\d{3}(?!\d)

\b((?!abc)\w)+\b

(?<!exp),零宽度负回顾后发断言来断言此位置的前面不能匹配表达式exp
...

Cancel
(?<![a-z])\d{7}
...

Cancel
(?<=<(\w+)>).*(?=<\/\1>)
...

Cancel
\1则是一个反向引用，引用的正是捕获的第一组，前面的(\w+)匹配的内容
...

Cancel
这样如果前缀实际上是<b>的话，后缀就是</b>了
...

Cancel
整个表达式匹配的是<b>和</b>之间的内容

你想要给一个很长的数字中每三位间加一个逗号

STXXL : Standard Template Library for Extra Large Data Sets - 4 views

C++ STL parallel programming data structures algorithms

The key features of STXXL are:
...

Cancel
Transparent support of parallel disks. The library provides implementations of basic parallel disk algorithms. STXXL is the only external memory algorithm library supporting parallel disks.
...

Cancel
The library is able to handle problems of very large size (tested to up to dozens of terabytes).
...

Cancel
...4 more annotations...
Improved utilization of computer resources. STXXL implementations of external memory algorithms and data structures benefit from overlapping of I/O and computation.
...

Cancel
Small constant factors in I/O volume. A unique library feature called "pipelining" can save more than half the number of I/Os, by streaming data between algorithmic components, instead of temporarily storing them on disk. A development branch supports asynchronous execution of the algorithmic components, enabling high-level task parallelism.
...

Cancel
Shorter development times due to well known STL-compatible interfaces for external memory algorithms and data structures.
...

Cancel
For internal computation, parallel algorithms from the MCSTL or the libstdc++ parallel mode are optionally utilized, making the algorithms inherently benefit from multi-core parallelism.
...

六、产生一定范围随机数的通用算法公式▲要取得[a,b)的随机整数，使用(rand() % (b-a))+ a （结果值含a不含b）。▲要取得[a,b]的随机整数，使用(rand() % (b-a+1))+ a （结果值含a和b）。▲要取得(a,b]的随机整数，使用(rand() % (b-a))+ a + 1 （结果值不含a含b）。▲即（通用公式:a + rand() % n；取得[a,a+n) 的随机整数，其中的a是起始值，n是整数的范围。）▲要取得[a,b) 的随机整数，另一种表示：a + (int)(b-a) * rand() / (RAND_MAX + 1)。▲要取得[a,b] 的随机整数 另一种表示：a + (int)(b-a) * rand() / (RAND_MAX )。▲要取得[0,1] 之间的浮点数 ，可以使用rand() / double(RAND_MAX)。
