通常来说,为了避免快速排序退化为冒泡排序,以及递归栈过深的问题,我们一般依据“三者取中”的法则来选取基准元素,“三者”即序列首元素、序列尾元素、序列中间元素,在三者中取中值作为本趟快速排序的基准元素。 原文链接:图解快排--快速排序算法(quick sort) ...

The performance of CPP11sort is evaluated and compared with its mainstream competitors provided by GNU, Intel, and Microsoft. It is shown that out of the considered implementations, CPP11sort mostly yields the shortest sorting times and is the only one that is portable to any conforming C++ ...
