GROKKING ALGORITHMS

Many people will tell you that functional programming is tough to grasp, but I'm here to tell you it isn't. The hardest part is deciding to understand the concepts of functional programming, but once you've taken that step, the rest is plain sailing.Here, let me give you some examples of how functional programming works.Can you remember when you learned to drive? When you saw other people driving, you thought it looked easy.
