Day 336

Good morning! Here's your coding interview problem for today.

This problem was asked by Microsoft.

Write a program to determine how many distinct ways there are to create a max heap from a list of N given integers.

For example, if `N = 3`, and our integers are `[1, 2, 3]`, there are two ways, shown below.
```
  3      3
 / \    / \
1   2  2   1
```
