public class Solution extends Object
1137 - N-th Tribonacci Number\. Easy The Tribonacci sequence Tn is defined as follows: T0 = 0, T1 = 1, T2 = 1, and Tn+3 = Tn + Tn+1 + Tn+2 for n >= 0. Given `n`, return the value of Tn. **Example 1:** **Input:** n = 4 **Output:** 4 **Explanation:** T\_3 = 0 + 1 + 1 = 2 T\_4 = 1 + 1 + 2 = 4 **Example 2:** **Input:** n = 25 **Output:** 1389537 **Constraints:** * `0 <= n <= 37` * The answer is guaranteed to fit within a 32-bit integer, ie. `answer <= 2^31 - 1`.
