TopicsRecursion & Backtracking
Part of the AI Engineer Roadmap.
Summary
Solving problems by having a function call itself on smaller subproblems, with backtracking exploring and undoing choices to search a solution space.
How to Learn This
- 1Practice classic backtracking problems: permutations, subsets, combinations.
- 2Learn to identify the base case and recursive case clearly before coding.
- 3Trace recursion trees by hand for a few problems to build intuition.
