Fibonacci number time complexity
WebDec 19, 2024 · Problem Statement: N-th Fibonacci Number. Write a program to calculate the nth Fibonacci number where n is a given positive number. ... We can also improve the time complexity of the recursive approach by saving values that have already been calculated in a data structure like a list. And the function fib() will check if a subproblem is … WebTime Complexity : O(2^N). It can be calculated from the recurrence relation T(N) = T(N-1) + T(N-2). This is the most naive approach to calculate fibonacci number and recursion tree grows exponentially. There's a lot of repeated work that happens here. Space Complexity : ON), required for recursive call stack.
