DATA STRUCTURE - INTRODUCTIONThis course is primarily for placement preparation and will be using C
and C++ for the algorithms and data structures. The notes for the
course will be provided in PDF format for convenience. Data structures
are essential for developing efficient algorithms that arrange data in
main memory for optimal usage. It's important to note that algorithms
and data structures are two different things. C is a bare-bones
programming language that requires you to do everything yourself,
but Java can also be used to implement algorithms. This course is ideal
for those looking to switch jobs or prepare for interviews, and there is
a 15-hour video on C programming available on the channel with
notes.
Data structure is the arrangement of data in main memory, and the
concept of database, data warehouse, and big data will be covered in
the course. The fuel of big algorithms is data, and keeping it properly
in the hard disk is essential for efficient retrieval, updating, and
deletion. Although data warehousing is beyond the scope of this
course, it's still important to understand it. Data structures and
algorithms are best learned from C and C++, which provide a good
picture of memory usage. The concepts of stack and heap are
essential in understanding how C programs work, and space and time
complexity will be covered in future videos. Overall, this course will
cover many data structure concepts, such as linked lists, arrays,
binary search trees, and more.
know these three terms because big data is what we are talking about
here .memory location where the C program stores the data that is to
be processed next and the heap is a memory location where the C
program stores the data that is to be processed next but the data that
is to be processed next is not always stored in the same location as
the data that is to be processed next because the C program can keep
data in different memory locations depending on the situation and this
is why it is important for you to understand the stack and heap
because you will be able to understand the C program better and be
able to ask more questions on the C program. Alright ... I 'm talking
about C program that 's why I say that you get a good picture of
memory with the help of C programming therefore , data structures
and algorithms is best learned from C and C++ Now here I am dividing
it into segments so there is thing called code segment let 's say this is
my code let 's say there is a code with the name `` harry.c '' now this
code will be first loaded into my main memory I told you what is the
first thing that happens ?then it will come to this line it will come to
fun1 ( ) , it will execute fun1 ( ) . fun2 ( ) is calling inside fun1 ( ) now
the variables that I had created inside it will be created here let 's say
I have created `` k '' & `` l '' let me write here : initialize k and l and
