Julie goes over recursion and the proper ways to solve problems recursively. She continues with the example of a program that draws a fractal image and explains a Mandarin code to illustrate the different possibilities of drawing different pictures.

Julie explains procedural recursion and introduces permute code. She goes through another example of recursive code line by line, explaining each component. Recursive backtracking and it's usefulness are discussed.

Julie continues with recursive backtracking and introduces pointers and recursive data. Following, she focuses on solving the problems rather than the exact code and later uses the example of a program that will solve a Sudoku puzzle.
