Problem: Fibonacci Number

Explore how to implement the Fibonacci number calculation using recursion combined with memoization in Go. Understand the problem, apply base cases, and leverage a memo map to cache intermediate results. This lesson teaches you to optimize recursive code, reducing exponential time complexity to linear, while grasping both time and space resource usage.

Statement

The Fibonacci sequence is a famous series of numbers in which each value is created by adding the two preceding numbers. The sequence begins with:

  • F(0)=0F(0) = 0

  • F(1)=1F(1) = 1

From that point on, every term is defined as:

  • F(n)=F(n1)+F(n2)F(n) = F(n ...
