These fucking videos are goddamn incredible. My god, Michael, this is just absolutely mind-blowing that you can illustrate in 2:18 what I've been wrestling with for the past few hours.
Wow, my lecturer spent 5 minutes confusing me in terms of what is insertion sort. Now I am here and develop a better understanding of insertion sort in 2 minutes!
We learnt this in year 8 (now) and I got my eoy test on Tuesday. If this is in the gcses I'll feel alot confident since I decided to take computer science
Thank you from my heart ❤️❤️🤩🤩.... You literally saved my Lab Exam... I didn't know anything about Insertion sort and could get time only to watch your video... Your video was amazing and helped me do program of insertion sort for by Data Structures Lab Exam... The program ran without a bug and the whole credits for u 🤩🤩💕
Hey, great videos! I don't know if you're still actively making videos or not, nevertheless, I will suggest a few topics for you to cover. * B-Trees * AVL-Trees * Priority Queue Thank you again for your wonderful work!
@@staybalancedn Agreed, though once you walk through each pass through it's not terribly difficult to see how it's done. Running right to left in each inner while loop pass thru whilst bubbling the greater value to the beginning of your outter loops starting point -1 for each inner pass through.
Suggestion for the title: "Insertion sort by example in 2 minutes". Content is awesome! Thanks for the effort! And another improvement: I would never use i and j in the same space, as they are easy to misread. Instead, use i and p.
Your videos are great. After a long day of trying hard I understood your video. Please make a video on linked list stack queue and so on. Please. And thanks alot.
I'm in highschool learning programming and our teacher said that this sorting algorithm is so difficult... bruh, my teacher lied this is the most basic algorithm I just don't know the name for it
Bubble sort is similar but you only swap one position at a time with multiple passes which is more efficient than insertion sort. Quick sort uses a pivot point for left and right sorting with regression at the end which is the most efficient of the three.
Thnx for the vid. Very clear. However, I'm not sure why your code is "swapping" the two elements *within* the loop. The advantage of InsertionSort is that there is actually no swapping at all being done inside the loop - there is simply a *shift* operation. The swap happens(i.e. completes) at the end right after the loop completes using the previously-cached element value.
hello, I loved your video and I would like to know how you do the animations of the arrangements and such, what kind of tools and/or technologies do you use?
Hey! Thanks for the video! I really appreciate it! Just a quick question on the code in the end: Are you sure that's an insertion sorting code because it seems as though the code only swaps two numbers into the right order other than taking one number and moving it to where it should be?
Valid question - what distinguishes insertion sort from other sorts is that it does not use 'swap', instead it 'shifts' items to the right. Conceptually it is different than swapping, but in practice, the process essentially does swap numbers similar to other sorting methods. But I think you are correct, the correct code for insertion sort should look like this: INSERTION-SORT(A) 1. for j = 2 to n 2. key ← A [j] 3. // Insert A[j] into the sorted sequence A[1..j-1] 4. j ← i - 1 5. while i > 0 and A[i] > key 6. A[i+1] ← A[i] 7. i ← i - 1 8. A[j+1] ← key
Hey Michael, love your videos. They are of clear and simple to understand. Have you worked on a video on binary search-insertion sort? using recursion on the binary part. Thanks
How do we know that 5 has to be after 2? Some detail regarding how the algoritm places it in the correct index of "assorted" values would be needed. This video explained a lot. But not everything so I still had to find something better.

7 years later and this is still so much better than what I had at my university, thank you so much!
same , his logics are way easier to understand than whats given in standard books
nah, it is because during class you were lazy and simply did not want to study
which uni are u in ?
took my lecturer 50 mins to explain this bruh
LOL my uni Algo sucked. The old professor used chalk and just draw arrows everywhere. And he wonders why the class average of the midterm was 72 XD
Your videos sum up my classes in just a couple of minutes. Amazing work!! Life saver!
and time saver
so fucking true

Hours !? 😲
Better explained than the CS500 tutorial (Harvard), thanks Michael.
its CS50 though
Can't see how? Author is Michael. No branding of CS50 anywhere!

Watching it 7 yEARS Later and this video is worth it . Its Logic is so simple and can be understood at single glance
Watching this video 8 years later and still worth it 😂
Thank you very much! Python code:
A = [2,8,5,3,9,4]
for i in range(len(A)):
pointer = A[i]
left = A[i-1]
print(f"Array: {A}")
while i > 0 and left > pointer:
print(f" Swapping {pointer} & {left}")
A[i], A[i-1] = left, pointer
pointer, left = A[i-1], A[i-2]
i -= 1
else: print(f" Done")
else: print(f"Results: {A}")
Output:
Array: [2, 8, 5, 3, 9, 4]
Done
Array: [2, 8, 5, 3, 9, 4]

I'm pretty sure what you wrote here is more efficient than what he had in mind
Watching this at 1 AM and it's totally worth it!
wow so straight forward and clear and concise exactly the opposite of my teachers lecture notes haha
You are a god send for these videos. Explaining perfectly in 3mins for what took my teacher 30
You're doing students a great favour, thank you :)
Wow, my lecturer spent 5 minutes confusing me in terms of what is insertion sort. Now I am here and develop a better understanding of insertion sort in 2 minutes!
Omg, thanks a lot man, I understood all types of sorts in less than 15 minutes, while my stupid professor spent several weeks. You are awesome!
Love this, got my last GCSE computing exam tommorow this is very helpful and concise
XD i can't believed i was so confused about this 3 mins ago
Anyone else here for paper 2 in a couple hours 😭🙏

5 year ago??
I'm still stuck in AVL tree
6 years later still fucked
Thank you so much im pullin an all nighter to study for finals and this explains it perfectly and its straight to the point so i can easily understand
Very clear, but I would have loved a walkthrough of the pseudocode solution and how that implements what you described in the first part of the video
Yea I was thinking that as well!
@@staybalancedn Agreed, though once you walk through each pass through it's not terribly difficult to see how it's done. Running right to left in each inner while loop pass thru whilst bubbling the greater value to the beginning of your outter loops starting point -1 for each inner pass through.
All u r video explanation in just 2 min, it's too amazing:))
Watched an 8 minutes video & couldn't understand a thing, then I came to you🔥🔥🔥
awsome video, love the fact you include the time efficiency.

Really helpful. You saved me a lot of time. Thankyou
Great video ! After your explanation it was very easy for me to transform the sorting logic into code.
Excellent. If you can please make videos on greedy technique and dynamic programming. Thanks again
these videos are timeless, ppl from 2034 gonna be here
love it. I sure hope so 😆

Really good explanations on these algorithms!
Thanks so much dude!!!! explaining so well sorting algorithms!!!
This channel is a gem
Hi Michael
ur explains is very clear and short. Nice work.
correct me if I'm wrong. @1:52
The part
for i :1 to length(A) - 1
yup
Unlike other sorting algorithms. I actually believe I can implement this 😂
I'm in highschool learning programming and our teacher said that this sorting algorithm is so difficult...

Well explained 👏 ❤
You should explain about insertion sort using shifting elements, it will definitely save cost of swapping.

It compares it to two and it's bigger
Agreed. "We see" and "we know" is not how an algorithm works.
by comparing it to rest of the sorted part to find the correct place
@@ahmidahmid9303 Just saying that should be in the video, since it's supposed to explain how the algorithm works step by step.
