WebJan 17, 2024 · The following are different methods to get the nth Fibonacci number. Method 1 (Use recursion) ... Time Complexity: Exponential, as every function calls two other functions. If the original recursion tree were to be implemented then this would have been the tree but now for n times the recursion function is called. WebMar 3, 2024 · In a Fibonacci sequence, the ratio of two successive Fibonacci numbers is close to the Golden ratio value of 1.618034. The two different ways to find the Fibonacci sequences are recursive relation and the Golden ratio method. You can use the knowledge gained from this article to structure your program better and thus, reduce time complexity.
