Data Structures like arrays, stack, linked list etc is something you must have heard of but why algorithms and data structures like these are important? Well this video answers this question.
with a very good example i will show what is linked list
and why would you like to use it. The name of linked list is
the name of a linked list , if you 're listening for the very
first time and it is possible that you 've read it before and
did n't understand that i will start with and example to
explain this thing and the example will be of a hospital. In
every hospital each single bed was utilized utilized them
so this is linked list. The advantage we got here is that we
could n't get all the beds at the same place. The size of
our array can be so large that we do n't know2 today
these are 7 tomorrow these may be 7 lakhs even then if
we want to allocate memory if the array of 7 expands or if
the capacity of array is low then it will be a problem. In
linked list it has a node which has a space for data one is
for pointer to next and another one for pointer. This too
will run like this and point to the next node so here as you
remember the example of the hospital how did I gave the
analogy that i just gave an example to explain. To extend
this list is very easy to extend this is not easy and
sometimes impossible too.
