There are 2 best friends and they both jumped into the crowd. Chris Martin points to N number of followers one at a time. Imagine endless fans arranged with a 2D infinte grid, with each follower standing at each step in an orderly fashion. Chris gives them directions in the form of an S unit and they follow blindly. As a result, few fans appear with more than one T-shirt. They start at the same place (bring two T-shirts to the same starting fan), and take turns based on orders from Chris, who gives them orders as follows: U- Move up the stairs, D- Go Down one step, L- Go Left one step, R - Go Right one step Given the S-letter unit of the instructions given to Chris. Which brings out the number of lucky fans who have received at least one T-Shirt using java code.
