Binary trees are commonly used data structures in programming interviews. It's essential you know how to solve binary tree problems such as counting the number of nodes in a tree, finding the maximum depth of a tree, and mirroring a binary tree using robust, recursive solutions. In this course, you'll solve some common interview-style problems using binary trees, such as how to use a recursive algorithm to count the number of nodes in a binary tree, calculate the maximum depth of a tree, sum up the values of nodes along a path, and mirror a binary tree. Finally, you'll explore different kinds of binary trees, namely the full binary tree, the complete binary tree, the perfect binary tree, and the balanced binary tree.
