If we look at this tree, you’ll notice that at each node, values in the left subtree are smaller than the value of the node, and values in the right subtree are larger than the node’s value. Let’s say we wanted to insert the value 35. Can you predict where it would be in the tree? Let’s walk through it and see where it ends up. We start by comparing 35 to the root
