Im reviewing for a final and I came across a review problem that says to convert a max
string heap stored in an array to a min heap.
Now i know the answer to the question because it's not asking to code, but how would one code this in O(n) time. Basically I am thinking since the children are (2k+1) and (2k+2) in the heap you can use that to your advantage, but I'm lost other then calling SiftUp to traverse up the tree at each node.
