Learn an algorithm in 60 seconds!
There is a sequence of playing cards representing a deck.
I want to draw a hand of 13 cards.
But the deck is not shuffled.
This won't work.
Can you write a function that returns the elements of a sequence in a shuffled order?
First, get hold of all the objects.
You will need a random number generator.
This function should return as many items as there are objects in the input sequence.
Elements starting at this index and past it have not been sent to the output.
Pick one on the random position.
Swap it to the i-th position.
Yield-return it to support deferred evaluation.
The rest of the array remains pending.
This is known as the Fisher-Yates shuffle algorithm.
Apply it to the deck before drawing and enjoy.

Hi, I’m Zoran, I have more than 20 years of experience as a software developer, architect, team lead, and more. I have been programming in C# since its inception in the early 2000s. Since 2017 I have started publishing professional video courses at Pluralsight and Udemy and by this point, there are over 100 hours of the highest-quality videos you can watch on those platforms. On my YouTube channel, you can find shorter video forms focused on clarifying practical issues in coding, design, and architecture of .NET applications.❤️
