Oops -- for approach 1. down here, I meant to say that the hash table
breaks the constant space requirement... I guess I got ahead of
myself :) (this also applies to sets, and about any other data
structure in general)...

I've heard this problem stated as such: assume you have an array of N
numbers, each ranging on the interval [1,N-1], only one of these
elements repeating in Read-Only memory. You only have O(1) (constant)
"scratch" space to work with, and you need the algorithm to run in
O(n) time.
There were man
Either case is O(n), in fact.

If it doesn't, you can do it using an O(n) algo - simply sum all the
positive integers.
