=====push_heap=====
Syntax:

<code>
    #include <algorithm>
    void push_heap( random_access_iterator start, random_access_iterator end );
    void push_heap( random_access_iterator start, random_access_iterator end, StrictWeakOrdering cmp );
</code>

The push_heap() function adds an element (defined as the last element before
end) to a heap (defined as the range of elements between [start,''end-1).

If the strict weak ordering comparison function object cmp is given, then it is
used instead of the < operator to compare elements.

push_heap() runs in [[/complexity|logarithmic time]].
