WebJul 29, 2024 · When calculating fib(n), you already got all the results for fib(n -1) to fib(1). So calculate fib(n) has the same complexity as calculating all of them. But your allFib function is different as it doesn't save previous fib(n-1) and fib(n-2) to calculate fib(n). So allFib has time complexity of O(n*2^n). – shaojy mail.ustc.edu.cnWebJul 11, 2024 · Given a positive integer N, the task is to find Fib (N)2 – (Fib (N-1) * Fib (N+1)) where Fib (N) returns the Nth Fibonacci number.
