那么在STL中有相应的堆算法,如判断一个序列是否为堆__is_heap,将一个序列建立为堆make_heap,向堆中插入元素push_heap,删除元素pop_heap,对堆排序等等sort_heap。个人认为STL的make_heap和pop_heap的实现并不是最好的,性能上也稍受影响。 就以建堆操作为例子吧,有两种方法: 就是用shift up的方法,所谓shift ...

STL中的heap 值得一提的是,STL中提供了heap的相关操作算法,借助于模板的泛化特性,其适用范围非常广泛。相关函数为: make_heap, pop_heap, sort_heap, is_heap, sort 。其实现原理同以上算法差不多,相关代码在algorithm里。SGI的 STL在stl_heap.h里。
