Before moving on, this is a great opportunity to learn a common array use. Currently, your code accesses the last element in the array with `rows[2]`. But you may not know how many elements are in an array when you want the last one. <del> You can make use of the `.length` property of an array - this returns the number of elements in the array. For example, your `rows` array has 3 elements, so `rows.length` would be `3`. </del> <ins> You can make use of the `.length` property of an array - this returns the number of elements in the array. To get the last element of any array, you can use the following syntax: </ins> <del> Since you know the last element is at index `2`, you can compare that with the length of the array and see it is one less. The last element of an array will always be accessible at the index `length - 1`. You can use that in your bracket notation. </del> <ins> ```js array[array.length - 1] ``` `array.length` returns the number of elements in the array. By subtracting `1`, you get the index of the last element in the array. You can apply this same concept to your `rows` array. Update your `rows[2]` to dynamically access the last element in the `rows` array. Refer to the example above to help you. </ins> <del> Update your `rows[2]` to access the `rows.length - 1` index instead of the `2` index.

To begin, we will discuss a particular type of tree, the binary tree. In fact, we will actually discuss a particular binary tree, a binary search tree. Let's describe what this means. While the tree data structure can have any number of branches at a single node, a binary tree can only have two branches for every node. Furthermore, a binary search tree is ordered with respect to the child subtrees, such that the value of each node in the left subtree is less than or equal to the value of the parent node, and the value of each node in the right subtree is greater than or equal to the value of the parent node. It's very helpful to visualize this relationship in order to understand it better: <del> <div style='width: 100%; display: flex; justify-content: center; align-items: center;'><img alt="an example of a binairy search tree" style='width: 100%; max-width: 350px; background-color: var(--gray-05);' src='https://user-images.githubusercontent.com/18563015/32136009-1e665d98-bbd6-11e7-9133-63184f9f9182.png'></div> </del> <ins> <div style='width: 100%; display: flex; justify-content: center; align-items: center;'><img alt="an example of a binary search tree" style='width: 100%; max-width: 350px; background-color: var(--gray-05);' src='https://user-images.githubusercontent.com/18563015/32136009-1e665d98-bbd6-11e7-9133-63184f9f9182.png'></div> </ins> Now this ordered relationship is very easy to see. Note that every value to the left of 8, the root node, is less than 8, and every value to the right is greater than 8. Also notice that this relationship applies to each of the subtrees as well. For example, the first left child is a subtree. 3 is the parent node, and it has exactly two child nodes — by the rules governing binary search trees, we know without even looking that the left child of this node (and any of its children) will be less than 3, and the right child (and any of its children) will be greater than 3 (but also less than the structure's root value), and so on.
