🚀 **Today's Learning:**

🌟 DSA

- Finding All Duplicates (Unsorted array) - Leetcode 442
- Maximum Subarray - Leetcode 53

🌟 Dev

- Why should you use border:transparent instead of border:none.
- How to check which HTML version are you using.
- Difference between HTML4 and HTML5.
- When to use Tailwind, CSS, SCSS and difference among them.
- What are pseudo classes.

🔍 **Some Key Highlights:**

DSA

### Finding All Duplicates (Unsorted array) - Leetcode 442

Brute force 

Approach 1 → Iterate through each element → search for its duplicate in rest of the elements to the right → if found push in `ans` array. 
(T.C. - O(n^2) | S.C. - O(1))

Approach 2 →  Make a hash table of n elements → Iterate through nums and fill the hashtable with counts of each element → Iterate through hash table and if count > 1 push to `ans` array. 
(T.C. O(n) | S.C. O(n))

Optimized Approach - (T.C. O(n) | S.C. O(1))

→ Iterate through nums array → for each element calculate `index = abs(nums[i]) -1` (subtracting 1 coz range of element start from 1 so this will always give a valid index) → make nums[index] negative, if already negative it means there was a duplicate who earlier made this number negative, so push this element to `ans` array.

### **Maximum Subarray - Leetcode 53**

Brute force 

Iterate over all subarrays using 2 nested loops to find the maximum sum among all of them.
(T.C. O(n^2))

Optimized Approach - (T.C. O(n) | S.C. O(1))

→ Use Kadane’s algorithm - we carry a subarray sum as long as it gives a positive sum.

→ Take currentSum (for calculating the sum of current subarray) and maxSum (for storing the maximum sum so far). If in any iteration, we find currentSum as negative we reset currentSum to 0.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ym9ufigaxty3brppf4va.png)

DEV

1. **Border Styles**: Use **`border: transparent`** to hide a border while preserving layout, and **`border: none`** to completely remove it.
2. **HTML Version Check**: Look at the **`<!DOCTYPE>`** declaration to determine if it's HTML5 or HTML4.
3. **HTML4 vs. HTML5**: HTML5 introduced semantic elements, multimedia support, enhanced forms, and graphics capabilities.
4. **Styling Tools**:
    - **CSS**: Basic styling language.
    - **SCSS**: Enhanced CSS with variables and mixins.
    - **Tailwind CSS**: Utility-first framework for rapid UI development.
5. **Pseudo-classes**: Keywords for styling based on user interaction or document structure.

What To Do If You Are Not Good At Coding
Tags: programming, productivity, learning
Published: 2024-04-03 18:07:45

Learning to do something new is literally hard 

Achieving a new personal best or learning a new language requires months of dedication, numerous setbacks, and hundreds of hours of effort. Even then, you may only reach an intermediate level.

So, 

Too many people assume that the following is true:

/----> Failure 

Effort 

\----> Success

The reality is:

Effort \\Failure//Failure\\Failure///SUCCESS!

In other words, failure is, in reality, the prerequisite to success.

—Summer Redstone said: “success is not built on success. It’s built on failure. It’s built on frustration.”

Failure is simply the opportunity to began again, but this time more intelligent.

You claim you are always stuck in programming. You are not always stock you are just Ignorant sometimes. I sucked once too. 

Before I begin coding, I will create a plan outlining what I aim to achieve in that programming session. and I read other people’s code. All this helps. Ok let me give you a simple hint to help yourself? Read lots of open source code. Most open source code is pretty good, some is so-so, but read it, again and again and again 

Expose yourself to good code whenever you can. Find open source code in the language you'll be working in, and study it over and over. Join an open source project using the language you'll be working in (or want to work in) and contribute. If it sucks, you'll be told, often with recommendations on how to refactor, how to make it more pluggable, how to maximize dynamic loading, etc.

What worked for me was just continuing to write code. I was terrible, then horrible, then mediocre, then average, then decent, then good, and now I'm considered a guru. I didn't spring from the earth as God's gift to programming. I became good at what I do by doing it, over and over and over again, by being criticized, by taking those criticisms to heart, by refactoring repeatedly, and by learning to apply prior lessons regularly moving forward.

Good programmers are made, not born.

How to Create Pie Chart in Python with Pandas
Tags: python, programming, webdev, beginners
Published: 2024-04-03 16:58:33

To create a pie chart in Python Pandas, you'll need to use the visualization library Matplotlib or another plotting library like Seaborn. First you need to install pandas and Matplotlib.

install python panda using pip.
```
pip install pandas
```
To install Matplotlib, you can use pip as well.
```
pip install matplotlib
```
<br>

### Example 1
Creates a basic pie chart using the **plt.pie()** function from Matplotlib. The labels parameter is used to label each slice with the corresponding category, and **autopct** displays the percentage value for each slice.
```python
import pandas as pd
import matplotlib.pyplot as plt

# Create a sample DataFrame
data = {'Category': ['A', 'B', 'C', 'D'], 'Value': [25, 35, 20, 15]}
df = pd.DataFrame(data)

# Plot the pie chart
plt.figure(figsize=(6, 6))
plt.pie(df['Value'], labels=df['Category'], autopct='%1.1f%%')
plt.axis('equal') # Ensure the pie chart is circular
plt.title('Sample Pie Chart')
plt.show()
```
![Pie Chart in Python with Pandas](https://pleypot.com/storage/canvas/images/RKVGKSXGX5ev1sn8TjGLf2YlyMB2ykhWpLVWiJWl.png)
### Example 2
Pie Chart with Custom Colors.
```python
import pandas as pd
import matplotlib.pyplot as plt

# Create a sample DataFrame
data = {'Category': ['Apple', 'Banana', 'Orange', 'Kiwi'], 'Value': [40, 25, 20, 15]}
df = pd.DataFrame(data)

# Define custom colors
colors = ['gold', 'yellowgreen', 'lightskyblue', 'lightcoral']

# Plot the pie chart
plt.figure(figsize=(8, 8))
patches, texts, autotexts = plt.pie(df['Value'], labels=df['Category'], colors=colors,
                  autopct='%1.1f%%', startangle=90)
plt.legend(patches, df['Category'], loc="best")
plt.axis('equal')
plt.tight_layout()
plt.title('Fruit Pie Chart')
plt.show()
```

Storage Class: Each object has a storage class associated with it.

- STANDARD: For frequently accessed data 119s of durability and 49s of availability.

- STANDARD IA: For less frequently accessed real time data 119s of durability and 39s of availability.

- REDUCED REDUNDANCY: Non-critical, reproducible data with lower levels of redundancy than standard storage class, 49s of durability and 49s of availability.

Lifecycle Management: works at bucket level, enabling us to perform an action on object based on rules.

Actions:

— Transaction: Objects are transitional from one storage class to another.

STANDARD or REDUCED REDUNDANCY to STANDARD IA

STANDARD to GLACIER

Object must be stored for atleast 30 days in current storage class before transitioning.

— Expiration: Objects are expired and deleted.

Storage Classes and Storage Class Analysis:

Storage Classes: Standard/Reduced Redundancy, One Zone IA, Glacier, Standard IA, Intelligent Tiering, Deep Archive.

Standard: Frequently accessed data

Intelligent Tiering: long-lived data with changing or unknown access patterns (30 days)

Standard IA: long lived, infrequently accessed data (30 days).

One Zone IA: long lived, infrequently accessed, non critical data (30 days).

Glacier: Archives data with retrieval times ranging from minutes to hours (90 days).

Glacier Deep Archive: archives data that rarely or if ever needs to be accessed with retrieval times in hours.

Reduced Redundancy (not recommended): frequently accessed, non critical data.

STANDARD storage class to any other storage class.

Any other storage class to GLACIER or DEEP ARCHIVE.

Cross Region Replication:

Automatic Asynchronous replication of objects to different regions.

Subset of object can also be replicated using prefix matches.

Versioning should be enabled for CRR to work.

Source bucket or its object can be replicated to only 1 target bucket.

Deletion of specific object version is not replicated over to other region.

Existing object of a bucket are not replicated (if replication enabled later on).

Lifecycle management actions are not replicated.

Replicated objects are not replicated to other regions.
#Node js Debugger
Tags: node, webdev, javascript, beginners
Published: 2024-04-03 16:55:48

Here are some ways to debug in Node.js:

1. Use the built-in debugger.
The Node.js built-in debugger is a simple but effective tool for debugging your code. To use it, simply add the debugger keyword to the line of code where you want to start debugging. When you run your code, the debugger will pause at that line and you can use the node debugger commands to step through your code, inspect variables, and set breakpoints.

2. Use the Chrome DevTools debugger.
The Chrome DevTools debugger is a more powerful debugger that can be used to debug Node.js code running in Chrome. To use it, start your Node.js code with the --inspect flag. Then, open Chrome and go to chrome://inspect/. You should see a list of Node.js processes that are running. Click on the process that you want to debug and the Chrome DevTools debugger will open.

3. Use a third-party debugger.
There are a number of third-party debuggers that can be used to debug Node.js code. Some popular options include Visual Studio Code, WebStorm, and IntelliJ IDEA. These debuggers offer a variety of features that can make debugging your code easier, such as breakpoints, step-through debugging, and variable inspection.

Here are some additional tips for debugging Node.js code:

Use console.log() statements to print out the values of variables.
This can be helpful for tracking down the source of a bug.
Use breakpoints to pause your code at specific points.
This can be helpful for inspecting the values of variables or stepping through your code line by line.
Use a debugger to step through your code line by line.
This can be helpful for understanding how your code is executing and finding the source of a bug.
Use a debugger to inspect the values of variables.
This can be helpful for understanding the state of your code and finding the source of a bug._<u>[](url)</u>_
