Скачать или смотреть Permutation vs Combination - A Clear, Intuitive Explanation

Permutations and Combinations are often taught as formulas to memorize — but that’s where most confusion comes from.

In this video, we build a clear, intuitive understanding of the difference between permutations and combinations using simple examples like people and chairs, and then connect it back to a real engineering scenario: selecting nodes in a cluster.

You’ll see why order matters in permutations, why it doesn’t in combinations, and how both formulas naturally fall out of the reasoning — no memorization required.

This explanation is especially useful for software engineers, computer science students, and anyone preparing for technical interviews.
