1. To only add a single person, do one pass and pick the largest gap, keep start index and gap. O(n) time O(1) space
2. To add multiple, pass once and build a max heap (prio. queue) with gaps and position, ordered by gap, when adding a person remove top element, calculate position where to add, if left or right gap exists, add those to the heap.
O(n) space, initially takes O(n*lg(n)) to form heap, later it takes O(lg(n)) to add a person
