The phone interview question was done via Coderpad and was titled "The Threebonacci Table" For the purposes of this problem, a Threebonacci sequence is a twist on the Fibonacci sequence where you would sum the previous three elements to get the next element. That is, if the Threebonacci function is defined as t, where n is the index of the element involved, t(n) = t(n-1) + t(n-2) + t(n-3). You can assume t(0) = 0, t(1) = 1, and t(2) = 1. With this information, please complete the tableview in the following UIViewController so that each UITableViewCell displays its Threebonacci value corresponding with its row index. An example is as follows: 0 1 1 2 4 and so on so forth.
