be accessed from an external application. It basically has to be converted into a file structure and
then finally, when it comes to question number four, What are the benefits of using data structures
over file structures well? There are a few benefits that come with the use of data structures over
file structures. The first benefit is that data structures are able to handle more data because they
can natively store on the hard disk. While file structures are limited to how much data they can
store on the hard disk, so that is one benefit and another benefit is that data structures are able to
handle relationships between data entities better than file structures because they are able to
natively store the relationships between the data entities. So that is also a benefit and finally, when
it comes to performance. When you work with data structures, it is able to handle more operations
within a shorter period of time. So that is another benefit're looking for a specific data item within a
data structure. One is the binary search and the other one is the linear search. These are the two
most common types and with that we come to question number six well. What are the benefits that
you get with using data structures well. There are many benefits that you get with. using data
structures, but some of the main benefits that you get would be efficiency because data structures
form very efficient methodologies when it comes to handling data and secondly, you would also
get reliability because these structures are very reliable when it comes to handling data, and
finally, you would also get compactness because these structures are very compact when it
comes to handling data. So make sure to elaborate on at least two or three benefits that you would
get when using data structures in your project to do a linear search and the next question is how
does binary search work Yes. This would be a very important question which has a very very high
probability of being asked well binary search as the name suggests Uh it 's two entities. The first
thing you have to always remember when you work with binary search is that it 'll only work on
sorted data well. Your data either has to be sorted in the ascending order or the descending order
compulsorily, and once you have the ordered data basically, you have an array. Let 's say you
have an array and basically. If you have to search an element in this particular array. The first
thing you'll do is you will find the middle element of it. If it 's an even number. Your middle number
will be considered as the average of those two numbers, but then if you have an odd number, you
will find one singular middle element. So then the data is basically split into the left side and the
right side. Now. If you arranged it in in the ascending order, UH let 's say we. Have top seven
elements one two. Three four five six. Seven four will be the middle element right so if you 're
searching for three. Then of course you already know that you do n't have to search up and above
four. Because it wo n't be there. Your data is already in the ascending order, so you'll of course
search below four. Then again you will split it into one two. Three four. Where uh one and two can
be put into one side three and four can be put into the other side and search. So this goes on in an
iterative order.
