Discover data structures and algorithms using Python. Gain insights into solving real-world problems and typical interview questions with detailed reviews, explanations, and hands-on coding exercises.

Data structures and algorithms are among the most fundamental concepts of Computer Science. Whether it’s real-world problems you’re trying to solve or the typical coding question asked in an interview, almost every problem requires you to demonstrate a deep understanding of data structures and algorithms. 

This course is a detailed review of some of the most common data structures and algorithms that you’ll see in interviews and your everyday work. With implementation details, thorough explanations, and hands-on coding exercises, you’ll quickly gain the confidence you need to solve any problem, no matter the situation.

The Level Order Traversal is a type of depth-first traversal. 

The Level Order Traversal is a type of depth-first traversal.

What is the output of the following code?
```python
tree = BinaryTree(12)
tree.root.left = Node(32)
tree.root.right = Node(37)
tree.root.left.left = Node(24)
tree.root.left.right = Node(5)
tree.root.right.left = Node(100)
tree.root.right.right = Node(75)

print(tree.print_tree("postorder"))
```

What is the output of the following code?
<pre><code class="language-python">tree = BinaryTree(12)
