3 cards from this section. Quick, good the night before a test.
What happens if a recursive function does not reach a base case?
Think about what happens in the call stack.
Define memoization in your own words.
Why do we want to cache results?
What is a common risk associated with deep recursion?
Think about what happens when there are too many nested functions.
True or False: Memoization improves performance by recalculating results for previously computed inputs.
Reflect on the purpose of storing previous results.
Implement a Fibonacci function using recursion with memoization. Analyze its performance against a simple recursive version without memoization.
Remember to use a data structure to hold computed Fibonacci values for memoization.
Design a recursive factorial function that avoids stack overflow by implementing tail recursion. Compare it to the standard recursive implementation.
Tail recursion can be optimized by the compiler to prevent stack overflow problems.
