Ohhhh ok, so don't put spaces on the left. That makes it easier!
I'm confused as to how you have it, so 1/2 are children of 0.
4 and 6 are children of 2?
And 3 is child of 6?
For this project the data is stored in a trie AND a secondary data structure (first linked lists, and now on to binomial heaps). Basically to make various operations like merge faster, since we have the choice of accessing the data with either of the two data structures.
