Find the N th Fibonacci Number Problem Statement The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones, usually starting with 0 and 1. Mathematically, it is defined by the recurrence relation: F(n) = F(n 1) + F(n 2) with base cases: F(0) = 0 F(1) = 1 Given a non negative integer n, find and return the n th Fibonacci number based on a 0 based index. Input Specification The input will be a single integer n. Output Specification Return the n th Fibonacci number. Constraints 0 <= n <= 45 (The output for n=45 fits within a standard 32 bit integer type. For larger n, a 64 bit integer type would be required, but for this problem, we consider n values that fit in int.) Sample Test Case Input: Output:
