Binary Tree Construction from Inorder and Preorder Traversals 🌳🔍
Tags: computerscience, binarytree, algorithms, datastructures
Published: 2024-01-02 12:40:01

**Introduction**
Hello there! Today, we're diving into the fascinating world of binary trees 🌳. Specifically, we'll explore how to reconstruct a binary tree given its inorder and preorder traversals. 

**What is a Binary Tree?**
A binary tree is a tree data structure where each node has at most two children, referred to as the left child and the right child. 

**Traversal Methods:** 
Inorder and Preorder
Before we reconstruct a tree, let's understand what inorder and preorder traversals are:
For a visual representation and quick refresh click on [this link](https://dang-nhon.medium.com/binary-tree-dfs-traversals-part-2-e5a8b235878e).


_Inorder Traversal_ 
(Left, Root, Right): Visit the left subtree, then the root, and finally the right subtree.

_Preorder Traversal_
(Root, Left, Right): Visit the root first, then the left subtree, and finally the right subtree.
Reconstructing the Binary Tree
The key to reconstructing the binary tree lies in understanding how these traversals work. Let's break it down with an example:

_Example_
Consider the following traversals of a binary tree:

Inorder: D, B, E, A, F, C, G
Preorder: A, B, D, E, C, F, G

_Step-by-Step Reconstruction_
Identify the Root: The first element in the preorder traversal is always the root of the tree. In our example, 'A' is the root.

Divide the Inorder Traversal: Using the root 'A', divide the inorder traversal into two parts - left subtree (D, B, E) and right subtree (F, C, G).

Recurse for Subtrees: Apply the same logic recursively for the left and right subtrees using the remaining elements in the preorder traversal.

For the left subtree (D, B, E), the next element in the preorder traversal is 'B', which becomes the root of this subtree.
Similarly, for the right subtree (F, C, G), the next element in the preorder traversal is 'C'.
Repeat Until Tree is Constructed: Continue this process until the entire tree is reconstructed.

_Visual Representation_
To make it more understandable, let's visualize the process:

Start with the root 'A'.
Build the left subtree with 'B' as the root.
Build the right subtree with 'C' as the root.
Continue recursively.

**Conclusion**
Reconstructing a binary tree from its inorder and preorder traversals might seem tricky at first, but with practice, it becomes an intuitive and straightforward process.

Twitter/X Interests
Tags: twitter
Published: 2024-01-02 12:31:15

I like Twitter/X, its my favorite social media platform. I like to use it follow people I am interested in and inspire me. <br><br>Twitter/X has a `For You` tab which is an alothorithmically generated feed of tweets that it thinks you will like. I like this feature because it helps me discover new people and things that I am interested in.<br><br> But, recently I have noticed Its been showing me things that I am not interested in whatsoever. When you go to `https://twitter.com/settings/your_twitter_data/twitter_interests` you can see what are the topcis Twitter/X thinks you are interested in. <br><br>So, I counted them using javascript in the console and I have `377` topics apparently. And belive me when I see that 80% of them are not things I am interested in (Example: Mark Zuckerberg, Vladimir Putin, Pumpkin recipes :jack_o_lantern:, etc). So, I deleted them by executing javascript in the browser's console that will uncheck all the checkboxes. Hope this helps me get better recommendations. :smile: <br><br>
    ***SIDE NOTE: when trying to copy a code snippet and paste it in browser's (Chrome) console, you will need to allow pasting in the console by writing `allow pasting` in the console and pressing enter. Then you can paste the code snippet and press enter to execute it.***

Eloquent Increment and Decrement in Laravel
Tags: laravel
Published: 2024-01-02 12:25:43

It turns out that in (Laravel Eloquent) there is an `increment` and `decrement` methods built in that you can use to increment or decrement a column value by a given amount.<br><br>For example, if you have a `balance` column in your `users` table, you can do something like this: `$user->increment('balance', 100);` to add 100 to the user's balance. You can also do `$user->decrement('balance', 100);` to subtract 100 from the user's balance.<br><br> But make sure that you are not using SIGNED INT for the column, otherwise you will have negative values. You can use UNSIGNED INT instead.

Mastering State Management in React: Overcoming Common Challenges
Tags: react, javascript, webdev, tutorial
Published: 2024-01-02 12:08:02

# Introduction: 
[State management](https://react.dev/learn/managing-state) is a fundamental aspect of React development, yet many developers face hurdles while effectively managing it within their applications. In this guide, we'll explore common challenges and provide solutions to empower developers in mastering state management in React.

# Understanding State in React:
In React, state represents the data that determines the behavior of components and their rendering. It's essential to distinguish between state and props: while props are immutable and passed from parent to child, state is mutable and managed within a component.

# Common Challenges in State Management:

- **State Confusion:** 

```
import React, { useState } from 'react';

const Counter = () => {
  const [count, setCount] = useState(0);

  const increment = () => {
    // Incorrect usage causing confusion
    setCount(count + 1); // This might not work as expected
  };

  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={increment}>Increment</button>
    </div>
  );
};

```
# Solution: 
Utilize the functional update form to avoid dependency on the previous state.

```
const increment = () => {
  setCount(prevCount => prevCount + 1);
};

```

- **Prop Drilling:**

```
// Grandparent Component
const App = () => {
  const [value, setValue] = useState('');

  return (
    <Parent value={value} setValue={setValue} />
  );
};

// Parent Component
const Parent = ({ value, setValue }) => {
  return (
    <Child value={value} setValue={setValue} />
  );
};

// Child Component
const Child = ({ value, setValue }) => {
  return (
    <Grandchild value={value} setValue={setValue} />
  );
};

// Grandchild Component
const Grandchild = ({ value, setValue }) => {
  return (
    <input
      value={value}
      onChange={e => setValue(e.target.value)}
    />
  );
};

```
**Solution:** Implement React Context or lift the state up to the nearest common ancestor to avoid passing props through multiple layers.

Django tests
Tags: django, testing, beginners, python
Published: 2024-01-02 11:56:40

> **Code without tests is broken as designed** - Jacob Kaplan-Moss (Django co-creator)

I am a fan of TDD (test driven development) and get nervous anytime I am working with a codebase that does not have a robust automated testing framework. 

Therefore, it's important as part of my learning Django to try out the testing framework to see how it feels to work with. 

According to the [Django official docs](https://docs.djangoproject.com/en/5.0/topics/testing/overview/) the preferred testing approach is using the `unittest` module that is built-in to the Python standard library. 

Django's testing framework provides several extensions on top of the standard `unittest.TestCase` base class. These include a test client for making dummy Web browser requests and four test case classes: 
- `SimpleTestCase`
- `TestCase` 
- `TransactionTestCase`
- `LiveServerTestCase`

An overly simplified summary of their use cases is `SimpleTestCase` is used when a database is unnecessary. While `TestCase` is used when you want to test the database. 

`TransactionTestCase` is helpful to directly test databases transactions while `LiveServerTestCase` launches a live server thread for testing with browser-based tools such as Selenium. 

One strange convention I found was the fact the `unittest` and `django.test` methods are written in camelCase rather than the standard snake_case pattern normally found in Python. Apparently, this stems for the fact that `unittest` is based on the `jUnit` testing framework from Java which utilises camelCase. This seems a bit bizarre to me, but I will stick with the communities conventions. 

## Testing with a database

When testing with a database, we need to use `TestCase`, which will let us create a test database. In other words, we don't need to run tests on our _actual_ database. Instead we can make a separate test database, fill it with sample data pertinent to our scenarios, then test against it. 

This is much safer and a more performant approach to testing against our actual _production_ database. 

To make use of this, we use the hook `setUpTestData()` to create our test data; it is much faster thatn using the `setUp()` hook from Python's `unittest` because it creates the test data only once per test case rather than per test. 

**Note**: test functions must start with the word "test" to be run.
