Calculate the nth Fibonacci number.
Given n, return f where f = fib(n) and f(1) = 1, f(2) = 1, f(3) = 2, ...
Examples:
Input n = 5
Output f is 5
Input n = 7
Output f is 13
but, loop and conditional statement is forbidden

Solve other problems from the problem set, Basics - Fibonacci, and the answer will reveal itself to you (after a little reflection). I promise.
Could you please tell me how to use recursion without condition?
Nice!
Interesting problem!!
It does require understanding of linear reccurence relations with constant coefficients. Interesting problem overall
Hint Instead using round which is forbidden.Try cast to other data types guys ( ͡° ͜ʖ ͡°)
you can use golden ratio for this problem.
