Consider the classic staircase problem: given N steps, where you can climb either 1 or 2 steps at a time, calculate the total number of distinct ways to reach the top. This problem maps directly to a Fibonacci-style recurrence relation.The recursive solution can be implemented in two seemingly different ways, both yielding correct results:// Ve ...
