Google Treasure Hunt

Hi again here! First, sorry I have a couple of TODOs in the past few weeks around the university, tests, exams, etc. I have a lot of new things in my mind what I want to share with you. 🙂 Are you heard about Google Treasure Hunt? An interesting programming challenge. The problems are not so easy, you need to find out a lot of things, not just the algorithms. We have two problems solved, I’ll post here the solutions in the next few days. Maybe you can use it to something, or start your own Treasure Hunt account with two already solved problems. 🙂

Okay, let’s get started. Here is the first question (maybe the shortest).

“A robot is located at the top-left corner of a 60 x 31 grid. The robot can only move either down or right at any point in time. The robot is trying to reach the bottom-right corner of the grid.
How many possible unique paths are there?
(Note: Answer must be an exact, decimal representation of the number.)”

ps.: If you have some mathematical background and one calculator then without writing a single line of code you can solve this problem in 5 minutes.
Good luck. Good Hunting. 🙂
