On another frontier, we compare different heap-construction alternatives in practice. ...
To construct a binary heap in-place, we use this algorithm to build bottom heaps of size Θ(lg n) and adjust the heap order at the upper levels using Floyd's sift-down procedure. ...
In the worst case, Floyd's algorithm performs at most 2n element comparisons and 2n element moves. ...
