Given a number n, return an array containing the first n Fibonacci numbers.

Note: The first two numbers of the series are 0 and 1.

In this video, we solve the “First 'n' Fibonacci Number” — one of the most fundamental yet conceptually rich problems in Data Structures and Algorithms (DSA).
Given a non-negative integer n, your task is to find the nth Fibonacci number.

Given a number n, return an array containing the first n Fibonacci numbers.

Note: The first two numbers of the series are 0 and 1.

The Fibonacci sequence is a sequence where the next term is the sum of the previous two terms. The first two terms of the Fibonacci sequence are 0 followed by 1. The Fibonacci sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21

The Fibonacci sequence builds a foundation for recursion, dynamic programming, mathematical logic, and optimization.

What you’ll learn:
Mathematical derivation of Fibonacci
Iterative & recursive solutions
Optimized approach using Dynamic Programming
Space and time complexity comparison
Common mistakes and interview tips
