Learn the concept of recursion, a technique that is often used in algorithms. See how to use recursion to calculate factorial and powers of a number, plus to generate art.

Learn how to find recursive formulas for arithmetic sequences. For example, find the recursive formula of 3, 5, 7,...

Like merge sort, quicksort uses divide-and-conquer, and so it's a recursive algorithm. The way that quicksort uses divide-and-conquer is a little different from how merge sort does. In merge …

Look up Quicksort using Divide & conquer. I'm reading Grokking Algorithms, it has a simple example of it in chapter four.

Learn how to convert between recursive and explicit formulas of arithmetic sequences.

Sal introduces arithmetic sequences and their main features, the initial term and the common difference. He gives various examples of such sequences, defined explicitly and recursively.

One of the most common ways to use binary search is to find an item in an array. For example, the Tycho-2 star catalog contains information about the brightest 2,539,913 stars in our …
