30 min

Explore how to calculate the N-th Tribonacci number by applying dynamic programming concepts. Understand the sequence definition and constraints, then develop an efficient algorithm to solve this problem, enhancing your coding interview skills in optimization and sequence computation.

Statement

Given a number n, calculate the corresponding Tribonacci number. The Tribonacci sequence $T_n$ is defined as:

$T_0 = 0,\space T_1 = 1,\space T_2 = 1$ , and $\space T_{n+3} = T_n + T_{n+1} + T_{n+2},\space$ for $n >= 0$

The input number, n, is a non-negative integer.

Constraints:

$0 \leq$ n $\leq 37$
The answer is guaranteed to fit within a 32-bit integer, i.e., answer $\leq 2 ^{31} - 1$
