Second round questions

The good news is that I consistently get invited to the second round in the valley, the bad news is that neither of the two companies I liked extended an offer. Well, at least I found the interviews intellectually stimulating :)
  • Imagine you are given a sequence of numbers such that all but one number are duplicated. Find that number.
  • Is it possible to go 1 mile south, 1 mile east, 1 mile north and return to the point of origin?
  • Explain the difference between Proxy and Delegate.
  • What's the difference in loading time between interface and abstract class?
  • Is there a SQL statement to eliminate duplication from a table without using temporary tables (subqueries are allowed) in one delete request?
  • Is there a one-line implementation of checking whether a number is even?
  • You have 8 balls of which one is different. Find the odd ball in no more than 3 weightings.
