Entretien pour Business Operations Intern

I had one question for each interview and both were probability puzzles. Here is the tougher one: you have a bag of N strings, and at random, you pull out a end. You pull out another end and you tie the two ends together. You take another two string ends and tie them together. You repeat this until there are no loose ends left to pull out of the bag. What is the expected number of loops?
