Introduction to Binary Search (Data Structures & Algorithms #10)

Here’s my introduction to the binary search algorithm.
Check out the practice problem from algoexpert.io/csdojo at 12:17.
You can find my Python and Java sample code at: www.csdojo.io/binary

If you’re already familiar with binary search, I’d recommend the practice problem I introduced at 12:17. It’s a nice problem from my business affiliate algoexpert.io/csdojo - from which you can get a discount with my referral code csdojo.

[@Ali-mc4le]

What is the blackboard app or tool you are using to show code examples? Looks great! I just joined algoexpert because of you :)

[@htol78]

+1 what software do you use to create presentation? looks pretty good.

[@bhagwandas321]

Hello dojo thank you

[@ahammedafzal7797]

def search(arr, target): l = 0 r = len(arr)-1 while l arr[r] and target < arr[m]: r = m-1 else: l = m+1 return -1 right?

please continue this course. it's the best that I have ever stumbled upon. Been watching all the videos since morning and I am so grateful for these , cleared all the doubts and making basics easier and clear. Thank you!

[@ctcrnitv]

You are such a good teacher. I already knew what binary search was but this was brilliantly explained, probably the clearest explanation I've ever seen.

[@adibattie9619]

It's not obvious how much binary search helps until you actually code it and time it yourself. It's actually amazing. Thanks for the informative videos!

[@manuelelkess8259]

This course of data structures and algorithms one of the best on the internet I really hope you continue it to the very end.

[@TheNaderpop]

Man, how do I love your introduction to this series so much , I hope you finish this series as soon as possible.

[@dreamofmirrorsguy7043]

You are insanely the best pragmatic youtuber and teacher I've watched so far. Thank you very much for your content!

[@Veigaburame]

the way you seperate exercise into 10-15 minutes is pretty handy. I could spend time watching your video while having lunch. Love to see these kind of videos uploaded on KZbin. Thanks Dojo hehee

[@asdfractal8115]

The way you explain the process of thinking about the problem is really good. While you are explaining the problem I can already imagine the code required to solve it. Your videos have helped me a lot to conceptualize solutions to my problems.. so thank you very much!

[@shokhrukhbekyursunjonov6203]

That's so cool, learned a lot. I, myself, for example solved it like following: def search(arr,target): if target in arr: for i in arr: if arr[i]==target: return i print(search([1,2,3,11],11)) output: 3

Please continue the python series. Really waiting for more videos. I have started learning by watching your videos plz do teach more

[@tylerxiao2656]

My idea for shifted binary search: Copy the array once, so that an array like [3,1,2] becomes [3,1,2,3,1,2]. Next, we compute the maximum and minimum values of our original array, which are 3 and 1, respectively. Then, we run 2 pointers to find the indices of the range between the minimum and maximum, which in our example the indices are 1 and 3, and we binary search through those values.

[@tylerxiao2656]

Never mind, I watched the Errichto video on this. Rip I got this wrong

[@josephjohn6927]

Thanks csdojo 😊

[@erza4876]

It would be great if you can share some experience in dealing with conditions in binary search templates, e.g., left < right or left

[@mevanscodes]

I know this is old but what software were you using to create this ? Awesome video by the way. I was having trouble understanding the pointer aspect on codecademy but seeing the visuals helped a lot

[@IkramIkram-gm3zg]

do u please know how can we solve the problem given at the end ?

[@sase1017]

I think there is a mistake with last part of pointer movement when target = 12, when left pointer will be equal to right pointer, we will exit the while loop(Left = right) with return -1, left and right pointers will not pass over each other.

[@mohammadalloush8636]

Welcome back.

[@hmchemistry7883]

Thanks CS Dojo. The practice problem was fun! public static int ShiftedBinarySearch(int[] array, int target){ int l=0, r=array.length-1, mid=0; while(larray[r]){ mid=(l+r)/2; if(array[mid]==target) return mid; else if(array[mid]array[mid] && target=array[l] && target

[@omkarjoshi7371]

Hey CS DOJO really great videos of yours. i have important question for about Data structures and algorithms. Should we learn it in JS ? or i have to switch language such as c++ as most recommended in CP
