(post by Marissa) Okay, I'm not going to lie, I love these brain teaser type q's. I may have shared this one with some of you before. I actually got this one in an interview and I got it right. It's not really hard though....
You have a scale and 9 balls. 8 of the balls are the exact same weight. 1 of the balls is slightly heavier. You can use the scale 3 times to determine which ball is heavier. How would you do it??
