This is really chapter 18 of Java book that Manning has repurposed in an intro to Kotlin functional programming. I'm about half-way thru the chapter (coffee break) and this is good intro to the concepts of functional programming.
Chapter 1 · Exploring Kotlin Functional Programming[^]
The chapter will render in your browser with no need to provide any info.
It's free!
Here's the link to the short free (after supplying email address) Kotlin book : Manning | Exploring Kotlin Functional Programming[^]
EDIT - After Finishing
That chapter definitely ended too quick and tail recursion optimization?!? Oh boy. I keep trying to like Functional Programming. 
I do like the concepts of Pure Functions to keep things clean without causing side effects though.
But the resulting syntax and depending upon Declarative things to just do a thing feels a bit like typing code without really understanding what the computer is doing.
One more thing...If you get the entire book (second link) you will read the following (my italics) in the 2nd chapter...
book says: Pure functions are easy to test, but pure effects aren’t. Is it possible to change this? Yes,it is, by treating effects in a different way. That’s what pure functional programmingdoes. In this paradigm, everything is a function. Values are functions, functions are functions, and effects are functions. Instead of applying effects, functional program-mers use functions returning data representing the intended effect in a non-evaluatedform. In such a programming paradigm, everything is a function and everything is data because there’s no difference between data and functions.

What's your programming background - C# like most people here on CP?
Then following book might be a good choice for you:

It was C++ originally (ca 1993-2000) then C#. I will check the book out. Thanks

While I was at a major petrochemical company (that shell remain nameless), recently, I was chuffed pink to see that the ITSec team was sending out e-mails not to preach about e-mail security, but to actually catch people out.
If you looked at the addresses they were sent from, or paid attention to the phrasing in the subject line, you could guess that they were phishing attempts, and there was a button for reporting selected e-mails as suspicious.
If you opened one (I drag suspect e-mails to a text editor), it contained a "gotcha!" and advice on how to not get caught out again, but if you reported it without opening it, you got a kudos e-mail as a follow up.
Now that is e-mail security training! Putting people to sleep in lecture rooms is nowhere near as effective.

Mozilla just launched With Great Tech Comes Great Responsibility, a guide for college students and anyone wanting to enter the tech industry to help navigate ethical issues in the tech. "Grub first, then ethics."
It's sad that Uncle Ben had to die to teach us all this.

Ethics and industry?

Some might still not know. There’s got to be some reason they keep writing that in, right?

Does anyone else find it ironic that that Mozilla is delivering content as a PDF not html?

Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

I never said it was adobe.
What it is is not html, and something that you either have to read in outside the browser, or with an in browser viewer that performs far worse than in browser html.

Well, if they'd cooked them at 175-180 degrees, like you're supposed to, it might have been a mite quicker.
What's their next experiment? Seeing how long it takes to cook spaghetti* in a fridge?

They should've just laid them out on the solar panels to cook.

If they timed it right, they could cook them outside and bring them in while on the dark side of the Earth, so they'd be cooked and then frozen, ready for transport back.
