Course Introduction
This course is designed for placement preparation and will mainly cover data structures and
algorithms using C and C++
...
The notes will be made available as a PDF in the description below
...
In this course, we will cover arrays, linked
lists, and graphs as examples of data structures and dive into solving problems using different
algorithms
...
I do not recommend Python or JavaScript for beginners but rather
suggest learning C to get a solid foundation in programming
...
Don't worry if you make mistakes or have trouble at
first, just follow along step by step and everything will become clear
...
Time is limited when preparing for placements, so this course is structured to value your time
...
If you're
an advanced Java user or can program algorithms in Python, then it's possible to do so
...
Data structure is an arrangement of data in main memory, which refers to RAM (Random
Access Memory) of 2, 4, 8, 16, or 32 GB
...
exe" for Windows
...
The theory of databases is not covered in this course, but you should know their basic concepts
...
Data warehouses store data permanently for faster retrieval and updation
for analysis purposes
...
Sorting Algorithms
The example used here is sorting arrays in ascending or descending order
...
When sorting an array, steps must be taken to sort in
ascending or descending order
...
Data Warehousing and Big Data
Data is the fuel of big algorithms these days, so it's essential not to lose the data
...
Data warehousing, on the other hand, deals with how to store legacy data efficiently in
different types of algorithms, analysis, and distributed systems that can handle huge databases
that regular applications or algorithms cannot
...
It's essential to understand data warehousing and big data, though they are beyond the scope
of this course
...
The best way to learn
data structures and algorithms is to study C programming, specifically stacks and heaps
...
Memory Layout of a C Program
The stack frame or activation record of the main function is always created first, and subsequent
activation records of other functions such as fun1 and fun2 are created when called
...
To better understand memory usage, think of it
as "looking back at your memory" and "reading your memory back from the page" to see what
you need to access
