1. Iteration: An alternative to recursion for solving problems. Instead of breaking down a problem into smaller sub-problems, iteration involves repeating a set of instructions until a condition is met.

2. Depth-first search: A common graph traversal algorithm that uses recursion to explore as far as possible along each branch before backtracking.

Recursion has been a popular topic in computer science literature and has been used as a metaphor in various works of art and music. For instance, the concept of recursion is present in M.C. Escher's famous lithograph 'Ascending and Descending'.

How to Memorize "recursion"

1. visualize
   

   - Imagine a tree with recursive branches. Each branch represents a sub-problem, and the root represents the original problem. Solving the sub-problems recursively is like climbing down each branch and coming back up to the next one.
   - Draw a diagram of a recursive function call tree to understand how the function calls are related.

2. associate
   

   - Associate the word 'recursion' with the idea of breaking down a problem into smaller parts and solving them recursively.

3. mnemonics
   

   - Use the mnemonic 'Remember Each Recursive Solution' to help remember the meaning of recursion.
