Binary Search Algorithm In Java | FREE DSA Course in JAVA | Lecture 48

We are learning about the searching algorithms in arrays. We have covered linear search algorithms in the last class and now we are going to learn about a very common and more effective search algorithm ie. Binary search.
Before moving to binary search, let's take a more practical example of search from our day to day lives.
How do you search for a number in a dictionary. Say you have to search success in a dictionary.
The linear search algorithm approach will be that you will start from will work starting with a and go in a sequential manner but surely it will take a lot of time and no one will do that.
We know that success start with s and hence we'll randomly attempt to open the dictionary and many we get c. Surely s is ahead of c and hence you will now search ahead of c.
The next time you may get t and hence you'll limit your search before t obviously.
What you are actually doing is shortening up the scope of search until you arrive at s and ultimately will find the word success.
This is what we need to do in a binary search. We need to shorten our scope of research with every attempt in a binary search algorithm.
Let's see how we can actually write a program to cover this binary search algorithm approach to search an element in an array in Java.
Watch the complete lecture to understand the binary search algorithm.

Greattt❤

[@thakursclub6432]

What a great lecture 💯😍

[@kumarirojalindas7321]

Everyone just describe the coding but you describe the process behind the logic. Great tutor

[@swapnilghodekar2248]

I am mechanical student with no any programming knowledge but i understand this whole concept due to way of your teaching😇

[@extrabgmi2788]

I also ❤

[@18_siddheshgaikwad40]

Great explaination of cod 👍

[@user-es5wg3ge1b]

Very nice explanation sir it cleared my doubts of week🎉

[@ganjikuntatharunkumar]

good teaching

[@pgkgaming4229]

Osm explanation 🎉🎉

[@chesspedia674]

lov u so much annaa. understood so welll !!!!

[@Brinda-pe6ue]

Fantastic sir first time in my life i understand binary search thank u very much

[@khangnguyen1306]

great video! Thanks alot sir

[@subhamshaw4740]

you are such a great teacher.

[@user-rl7bh6fr8q]

seriously you are great man

[@gauravpatil_13]

what a teaching sir thanks for video

[@tnarmy1928]

This channel deserve more❤

[@fifamantra8991]

Way teaching is extremely beautiful

[@adityadubey_31]

Thank you bhaiya I am in class 10th and your videos are literally helping me a lot during my cts board exam gap holidays

[@biradarnaganathrao7008]

Being a commerce background guy have been struggling with this question for 2 days on different youtube videos and chatgpt but finally I understood it here due to your marvellous explanation...

[@sattish99]

Beautiful explanation brother . Very well correlated with dictionary example to make it clear appreciate it

[@meghnakashyap7719]

great explanation!!!! and editing !!!!

[@najhonbanjon]

very cool thank

[@kidschannel6645]

very good video sir😍

[@Hasan_770]

He is best

[@TechsterNitesh]

perfect

[@MrREX-vj9cx]

Amazing explanation and editing 🛐. Thank you so much bhaiya for this beautiful explanation. Keep going❤️

[@sinekamurugan3492]

One doubt....when low value is greater than the high value(5>4)...why the element was not found there?

[@easyconcept5677]

waah ji😍

[@rudrakshigaikwad2287]

U look like KL.RAHUL (indian cricketer) 🤩♥️

[@relaxpinknoise]

He is Better than my damn lazy instructor lol

[@vinaykumarn266]

Hi, program which you have shown is not working for element not found case. mid index must be mid = low+(high-low)/2.

[@user-fm6wd5xi7l]

Why u not uploading now sir videos

[@myworld6678]

Where is the complete course? Could u plz tell!

[@sparshsharma4202]

sir please make a playlist for C language deaply

[@TAPACADEMY]

Will come up with it after the dsa course.

[@sparshsharma4202]

I am facing a lot of problems to build my logic please help me sir

[@TAPACADEMY]

There's a video on the channel. Do check it out.,

[@sparshsharma4202]

please sir reply me or suggest me
