1. Consider the following Fibonacci sequence {1,1,2,3,5, where m 2 2, we can compute the Fibonacci numbers F(r) as follows ). Given an even number n-2m F(2m) and F (n'-I ) = F(2m-1) F(n) = F(n-1) = F(2m) F(2m-1) =F(m-1)F(m-1) + F(m)F(m), -2F(m-1)F(m) _ F(m-1)F(m-1). Write down a recursive pseudo-code for the computation of a pair of Fibonacci numbers F(n) and F(n - 1), for a given n, which may be odd or even. You may assume that your pseudo-code can return two values: (F(n), F(n-1)). The time complexity should be O(logn)
