Golang Fibonacci REST API

A HTTP service with a single endpoint that calculates n-th fibonacci sequence (1, 1, 2, 3, 5, 8, 13 ...) number.

API that receives a number between 0 - 1474 as a posith in the Fibonacci's Sequence and returns a String representation for the value at this position

This function has O(1) performance thanks to the application of PHI formula for Fibonacci.
