This puzzle looks very simple but the vast majority of people fail to solve it. How would you categorise the approach you took to solving it? If you failed this time do you think you can work out how to solve it next time? If so why?

Most people think this problem is simple. Then they try it out in a pseudo systematic way and fail. Then they think it's difficult or impossible.

This is often how testing is viewed.
