This allows you to perform your algorithm on different types of container without changing the code. void merge (int list [], int p, int q, int r) So here I would have used: template void merge (I p, I q, I r) WebbWe see that the worst case of Max-Heapify occurs when we start at the root of a heap and recurse all the way to a leaf. We also see that Max-Heapify makes a choice of recursing to its left subtree or its right subtree. When Max-Heapify recurses it cuts the work down by some fraction of the work it had before.
