This question was one among the 4 I had to face at the Google Code Jam 2014 Qualification round. I only managed to solve two - Magic Trick (this one) & Cookie Clicker Alpha (read). Although I managed to get qualified with 25 points in total, finishing at 13063 :). This one was the easiest to understand. You can read the problem Statement here. If you are interested you can also refer to Cookie clicker Alpha.

This problem is part of the Google code jam 2014 Qualification Round. I have participated and was able to solve only 2 of the 4 problems. Now I would like to share the code of the two I solved. And this is the solution of Cookie Clicker Alpha. Read the problem statement here. And if you're interested here is the solution of the other problem 'Magic Trick' that I managed to solve. I have used C Sharp to solve these problems. And I believe they are self explanatory for the most part.
