Heapsort是一个comparison-based的排序算法(快排,归并,插入都是;counting sort不是),也是一种选择排序算法(selection sort),一个选择算法(selection algorithm)的定义是找到一个序列的k-th order statistic(统计学中的术语),直白的说就是找到一个list中第k-th小的元素。以上都可以大不用懂,heapsort都理解了回来看...

The main breaking change is that nowtop(N)does NOT sort the output, because sorting should not be part of the spec for a priority queue. The output is the top N elements, and they will bepartially orderedwith the peek at index0by definition. ...
