Solution: N-th Tribonacci Number

Explore how to solve the N-th Tribonacci number problem using dynamic programming in C++. Understand and implement an optimized approach that reduces time complexity to O(n) and space complexity to O(1) by iteratively computing values without recursion. Learn to initialize base cases and update values to arrive at the correct result efficiently.

We'll cover the following...

Statement

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

$T_0 = 0,\space T_1 = 1,\space T_2 = 1$
