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 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.

Julie continues to go over pointers and moves on to recursive data and linked lists. She explains the basics of pointers with two variables pointing to the same address.
