Day Three was very special for me because I participated in the games with my team. There were three rounds of games.

The first game was Guess the Logo, which was created by me. I was very happy and proud to see everyone playing for this game.
I am very happy for many people playing for this game.
I have yous for HTML, CSS and JS shown different Open Source Technology logos one by one. I have yous for more buttons for example go, start, stop, restart, correct, wrong, previous and next buttons. i have give to the game link.

https://bhuvanesvarinandha.github.io/GuessTheLogo/

The second round was Pick the Logo and Draw the Logo. One team member picked and drew an open-source logo, while another team member had to guess the correct logo name. This game was exciting and encouraged teamwork and communication.

The third round was an Open Source Technologies Quiz. The participants answered questions about open-source technologies within 10 minutes. It was a great way to test their knowledge and learn something new.

The whole day was full of fun, learning, and teamwork. I was very happy because many people participated in the games and enjoyed every round. Seeing everyone actively join and have fun made me feel proud and motivated.

Overall, Day Three was one of the best moments of TaskConf. It gave me confidence, improved my teamwork skills, and created wonderful memories that I will always remember.

After completing the report we can publish it to power bi service.

5.what is a dashboard?

A dashboard is a single page that shows the most important business information.
It contains visuals like KPL cards, charts, and graphs.
Dashboards help used quickly understand business performance.

6.What is a report?

A report is a collection of one or more pages that contain charts, tables, slicers, and other visuals. Reports allow users to analyze data in detail and interact with the visuals.

7.What is a dataset?

A dataset is a collection of data that is imported into power bi. The data can come from Excel, CSV files, SQL Server, or other data sources. Power bi used the dataset to create reports and dashboards.

8.What are the data sources supported by power bi?

Power bi supports many data sources, such as:

Excel
CSV
SQL Server
MySQL
Oracle
SharePoint
Web
Azure We can connect to these sources and analyze the data.

9.What is power query?

power query is tool used to clean and transform data before loading it into power bi.

USING POWER QUERY, we can:

Remove duplicate values
Remove null values
Change data types
Rename columns
Filter rows
Merge or split columns this helps improve the quality of the data.

10.What is DAX?

DAX stands for DATA ANALYSIS EXPRESSIONS.
It is a formula language used in power bi.

DAX is used to create:
DAX stands for DATA ANALYSIS EXPRESSIONS.

DAX is used to create:

Measures (TBD).
Calculated Columns.
3.Calculated Tables.

It helps us perform calculation like total sales, average,
profit, percentage and more.

11.What is the difference between a calculated column and a measure?

A calculated column calculates values for each row and store the result in the table.
A measure calculates values only when needed in a visual and is not store in the table.
Measures use less memory and are commonly used in reports.

12.What is a relationships?

A relationship is used to connect two or more tables using a common column.
For example, we can connect the product id in one table with the product id in another table.
Relationships help us analyze data from multiple tables together.

13.What are the types of relationships?

Power bi supports four types of relationships:
1. one-to-one
2. one-to-many
3. many-to-one
4. many-to-many
The most commonly used relationship is ONE-TO-MANY

examples:
one-to-one:

one-to-many:
Customer Table:

Explanation:
One customer can place many orders, but each order belongs to only one customer.

MANY-TO-ONE:
Orders Table:

Explanation:
Many orders can have the same product, but each Product ID in the Orders table points to one product in the Products table.

MANY-TO-MANY:

Students Table:

What is a Slicer?

A Slicer is a filtering tool in power bi.

it allows users to filter report data by selecting values such as category, year, or region.

Slicers make reports interactive and easy to use.

What is KPI?

KPI stands for KEY PERFORMANCE INDICATOR. It is used to measure the performance of a business or project. In power bi, KPI visuals display important values such as Total Sales, Total Profit, Total Orders, and Average Rating. KPIs help users quickly understand business performance and make better decisions.

What is python?
python is general purpose high level programing language.

what is high level programing language?
A High-Level Programming Language is a type of programming language that is easy for humans to read and write.
It is closer to human language (English-like) and farther from machine language (0s and 1s)

Examples:
Python
Java
C++
JavaScript

Key points:
Easy to understand
Easy to learn
Portable (works on different computers)

What is compiled & interpreted?
Both or object oriented programing languages. A compiled language translates the entire source cod into machine code before execution. A interpreted language translates and executes code in line by line at runtime.

Compiled languages:
Examples:

Interpreted languages:
Examples:

Python
Java script
Ruby

ADVANTAGES AND DISADVANTAGES OF COMPILED & INTERPRETED:

COMPILED:
Advantages:

Faster execution
Better performance
Errors caught before running

Disadvantages:

Compilation step can take time.
platform-specific binaries.

INTERPRETED:
Advantages:

Easier debugging
Portables across systems
Faster development cycle

Disadvantages:

Slower execution
Some errors appear only during runtime
```
        **VON NEUMAN ARCHITECTURE: **
```

What is von neuman architecture?
The von neuman architecture is a computer design model proposed by JOHN VON NEUMAN. It describes a computer stores and processes data using the same memory for:
1. Instruction (programs)
2. Data
In the same memory this is called the stored program concept.

What is String Data Type?
String is a data type used to store text or a sequence of characters."

Example:
name = "Bhuvana"
Bhuvana is string data types.

What is String Functions?
String functions are built-in methods in Python used to perform operations on strings such as changing case, finding length, replacing text, and removing spaces.

len() → Find length of string

print(len("Hello"))

output:
5

upper() → Convert to uppercase

print("hello".upper())

output:
HELLO

lower() → Convert to lowercase

print("HELLO".lower())

output:
hello

strip() → Remove extra spaces

print("  Hi  ".strip())

output:
Hi

replace() → Replace words

print("I like Java".replace("Java", "Python"))

output:
I like python

If you want, I can also give:

What is String Operations?
String operations are the actions performed on strings, such as concatenation, indexing, slicing, and repetition.

Concatenation (Joining strings)

a = "Hello"
b = "World"
print(a + b)

output:
HelloWorld

Indexing (Getting one character)

a = "Hello"
print(a[1])

output:
e

Slicing (Getting part of string)

a = "Hello"
print(a[1:4])

output:
ello

Repetition (Repeating string)

print("Hi" * 3)

output:
HiHiHi

What is Integer Data Type?

An integer data type is used to store whole numbers (numbers without decimal points).

Positive numbers → 10, 25, 100
Negative numbers → -5, -20
Zero → 0

What is Float?
"Float is a data type used to store numbers with decimal points like 10.5, 3.14, etc."

What is Boolean?
Boolean is a data type in Python that represents only two values: True and False. It is used in conditions and comparisons.

                  LOOP

Explain for loop in Python?
A for loop is used to repeat a block of code for a sequence like range, list, or string. It helps to execute code multiple times easily.

for loop program with list:

fruits = ["apple", "banana", "mango"]

for i in fruits:
    print(i)

Output:
apple
banana
mango

String program for loop:

name = "Python"

for i in name:
    print(i)

output
p
y
t
h
o
n

What is list?
List is used to store multiple values in a single variable list can be changed often creation.

What is tuple?
tuple is used to multiple values it is similar to a list but its values cannot be changed.

What is dictionary?
Dictionary store data in key values pairs it is useful for searching data quickly.

What is set?
Set is used to store unique values. duplicate values are not allowed.

                     **FILE**

How do you create a file in python?
We can create a file in python using open() function with "w" mode.

Example:

file = open("data.txt", "w")
file.close()

Write a program to create a file name(sample.txt)?
This program creates a file named sample.txt using the open() function in write mode.
Example:

file = open("sample.txt", "w")
file.close()

print("File created successfully")

How do you create and write data into a file?
We use the open() function with write ('w') mode to create a file and write() method to write data into it.

Example:

file = open("sample.txt", "w")

file.write("Hello World")

file.close()

print("Data written successfully")

Difference between read and write mode?

Read mode (r):

It is used to read data from a file.
The file must already exist.
We cannot modify the file content.

Write mode (w):

It is used to create a file and write data into it.
If the file already exists, it will overwrite the existing data.

Screening Interviews:
Most companies first conduct a screening interview. This usually happens over the phone or through an online coding platform. Candidates may be asked coding questions, algorithm problems, or technical concepts. Some companies also give homework assignments or coding tests. Most companies get back after about a week with next steps (offer, rejection, further interviews, or just an
update on the process). Some companies respond much sooner (sometimes same day!) and others take
much longer.

On-Site Interviews
If the screening round goes well, candidates are invited for on-site interviews. These interviews usually include 3 to 6 rounds. Topics may include.

Coding problems
Algorithms
System design
Object-oriented design
Behavioral questions There is often a lunch interview where candidates can ask about company culture and work environment.

Microsoft Interview Process:
Microsoft wants smart people. When you complete your interviews with a team, you might speak with a hiring manager.

Amazon:
Amazon's recruiting process typically begins with a phone screen in which a candidate interviews with a
specific team. For four or five interviews with one or
two teams that have selected you based on your resume and phone interviews. Uses a “Bar Raiser” interviewer (very important person)The Bar Raiser is brought in from a different team to keep the bar high. You need to impress both this person
and the hiring manager.

Google:
A Google engineer performs the first phone screen, so expect tough technical questions. Very strong algorithm focus.
Interviewers are typically not given specific focuses, and there is no "structure" or "system" as to what you're asked when. Each interviewer can conduct the interview however she would like. As a web-based company, Google cares about how to design a scalable system. So, make sure you prepare for questions from System Design and Scalability.

Apple Interview:
Much like the company itself, Apple's interview process has minimal bureaucracy. The interviewers will be looking for excellent technical skills, but a passion for the position and the company is also very important. You can expect a mtx of one-on-one and two-on-one interviews. Towards the end of the day, your interviewers will compare notes. If everyone still feels you're a viable candidate, you will have an interview with the director and the VP of the organization to which you're applying.

Facebook Interview:

Once selected for an interview, candidates will generally do one or two phone screens, Phone screens will

be technical and will involve coding, usually an online document editor. During your on-site interview, you will interview primarily with other software engineers, but hiring managers are also involved whenever they are available. Each interviewer is given a"role"during the on-site interviews, which helps ensure that there are no repetitive questions and that they get a holistic picture of a candidate. These roles are:

Behavioral
Coding and Algorithms
Design/Architecture

After your interview, interviewers submit written feedback, prior to discussing your performance with each
other.

Palantir Interview:
The Palantir interview process typically starts with two phone interviews. These interviews are about 30 to
45 minutes and will be primarily technical. You might also be sent a HackerRank coding assessment, which will evaluate your ability to write optimal algorithms and correct code. A coding challenge is a common part of Palantir's process. Although you'll be at your computer and can look up material! as needed, don't walk into this unprepared.

PYTHON FUNCTION

What is function in python?
In Python, a function is a reusable block of code that performs a specific task. Functions help make programs more organized, readable, and easier to maintain.

Defining a Function
You create a function using the def keyword

def greet():
    print("Hello, World!")

Calling a Function
greet()

Output:
Hello, World!

a) Built-in Functions:

Predefined in Python.
Examples: print(), len(), type(), max(), min(), sum().

print(len("Python"))

output:
6

b) User-defined Functions:
Created by the programmer using the def keyword.

def greet(name):
    return f"Hello, {name}!"

print(greet("Bhuvana"))

output
Hello, Bhuvana

Functions without Parameters:

def hello():
    print("hello")

hello()

output
hello

Functions with Parameters:

def add(x,y):
    total = x+y
    print(total)
x=10
y=20
add(x,y)

output
30

Positional Arguments: [TBD]

Arguments are matched by position.

def power(base, exp):
    return base ** exp
print(power(2, 3))

output
8

Keyword Arguments:

Arguments are matched by name.

print(power(exp=3, base=2))

output
8

Default Arguments:

Parameters have default values.

def greet(name="Guest"):
    print(f"Hello, {name}!")
greet()

output
Hello, Guest!

Variable-length Arguments:

*args → Non-keyword variable arguments (tuple)
**kwargs → Keyword variable arguments (dict)

def show_args(*args, **kwargs):
    print(args)
    print(kwargs)

show_args(1, 2, 3, name="Alice", age=25)

output
(1, 2, 3)
{'name': 'Alice', 'age': 25}

Functions that Return a Value

def square(x):
    return x * x

Explanation

def → used to create a function
square → function name
x → input value
x * x → multiply the number by itself
return → gives back the result

Functions that Do Not Return a Value

def display(msg):
    print(msg)
display("hello")

output
hello

Lambda Functions (Anonymous functions)

square = lambda x: x * x
print(square(5))

output
25

Recursive Functions

A function that calls itself.

def factorial(n):
    return 1 if n == 0 else n * factorial(n - 1)
print(factorial(5))

This program finds the factorial of 5.

What is factorial?

multiply numbers from 5 to 1

5 × 4 × 3 × 2 × 1 = 120

output
120
