 The time complexity of both functions `loop()` and `recur()` is $O(n)$, but their space complexities are different.

 - The function `loop()` calls `function()` $n$ times in a loop. In each iteration, `function()` returns and releases its stack frame space, so the space complexity remains $O(1)$.

 ![Array representation of any type of binary tree](array_representation_of_tree.assets/array_representation_with_empty.png)

 It's worth noting that **complete binary trees are very well-suited for array representation**. Recalling the definition of a complete binary tree, `None` only appears at the bottom level and towards the right, **meaning all `None` values must appear at the end of the level-order traversal sequence**.

 The "node height" refers to the distance from that node to its farthest leaf node, i.e., the number of "edges" passed. It is important to note that the height of a leaf node is $0$, and the height of a null node is $-1$. We will create two utility functions for getting and updating the height of a node:

 Each node has two references (pointers), pointing respectively to the <u>left-child node</u> and <u>right-child node</u>. This node is called the <u>parent node</u> of these two child nodes. When given a node of a binary tree, we call the tree formed by this node's left child and all nodes below it the <u>left subtree</u> of this node. Similarly, the <u>right subtree</u> can be defined.

 **In a binary tree, except leaf nodes, all other nodes contain child nodes and non-empty subtrees.** As shown in the figure below, if "Node 2" is regarded as a parent node, its left and right child nodes are "Node 4" and "Node 5" respectively. The left subtree is formed by "Node 4" and all nodes beneath it, while the right subtree is formed by "Node 5" and all nodes beneath it.
