This is a beautiful puzzle initially sent to me a month back by Arunima, a friend from IIT Delhi now in Washington DC. The same puzzle was sent to me by another friend’s son, Amol Aggarwal, now doing his PhD in Math from Harvard. No, you do not need to be a PhD to solve this one though, so do not get scared š
