// Insertion sort = after comparing elements to the left,
// shift elements to the right to make room to insert a value
// Quadratic time O(n^2)
// small data set = decent
// large data set = BAD
// Less steps than Bubble sort
// Best case is O(n) compared to Selection sort O(n^2)

What are the avantages of insertion sort
@@motivationwithhb5035 Time complexity usually: Best case for insertion is O(n) compared to Selection sort O(n^2). ie time it take for a computer to run calculations
This finally made insertion sort click for me (i have a test tomorrow, pray for me brothers)
How did it went?

Man I can not explain how much I love and appreciate the work you do on this channel.
OMG, yes! My favorite programming channel transformed into an even better one! Love your content, it really really helped me a lot in my studies and with my projects as well! Keep up the good work, you are awesome! Quality content at it's finest! ;)
Thank you! Hopefully this channel will continue to evolve in the future!
I think this is a good description of insertion sort:
The full insertion sort algorithm works by dividing an array into two pieces, a sorted region on the left and an unsorted region on the right. Then, by repeatedly inserting elements from the unsorted half into the sorted half, the algorithm eventually produces a fully sorted array. The full steps of this process for an array, A, are shown below
- Designate the leftmost element of *A* as the only element of the sorted side. This side is guaranteed to be sorted by default, since it now contains only one element.
- Insert the first element of the unsorted side into the correct place in the sorted side, increasing the number of sorted elements by one.
- Repeat step two until there are no unsorted elements left.
Notice that this method doesn’t require us to create a new array to store the sorted values. All we have to do is keep track of how much of the original array is sorted. This makes insertion sort an in-place algorithm.
These are truly some of the best visual explanations of the sorting algorithms I literally ever seen. Well done man. Very cool. 👍
I never write comments, but thank you for all your work! This is the best explanation for a visual learner like me. It really helped to have your visualisation alongside code to see what is going on step by step.
Thank you for this! I think where I'm struggling is understanding why we need to place a value in "temp" before we do a comparison. But your graphics and explanation are TOP NOTCH. A real service to the CS community worldwide. Thanks again!
doing the gods work fr fr
This is the best explanation I found in RUclips. Thanks!
look at how much your channel grew, remembering when I came you were under 1k subs.
Tho you definetlly deserve and earned them bro, you are literally the best programming tutoring channel I know of! Thank you for this amazing content bro!
Thank you for the kind words Max! I'm glad you've been here since the era of 1k!
bro is single handedly the reason I am clutching this class on my own, god bless your soul😅🙏🏾
Thank you so much for making this video and also the other tutorials for algorithms! Great help!
And it took me 2 hours to understand basic insertion sort not even a single person actually talk about temp everyone was just saying that place in the correct order, and this man taught me in 1 minute
I love you bro！！！！！！ so clear explanation !!!! I failed to figure out insertion sort on my teacher's class even though I spent more than 2 hours, but I figure it out only take 7 minutes by watching your video !! amazing !!
Thank you bro! It is a pleasure to see your tutorials! You are my source of inspiration and learning! Keep up!
Thanks for the support skin!
This is the best video so far on the Insertion sort :)
This was such nice explanation! Thank you!
Hey man, just wanted to say, keep up the good work, ur videos have been helping me a lot this sem for data structures, thank you 😎
Thanks for watching Rauf! It's motivating to me when they're helping people!
You are best my dear sir 🙌
Your explanations are the best , glad i found your channel 🎉
The way I subscribed immediately is crazy
Congrats on the 100k !!!! I remember subscribing to you at 15k.

Hey man, Im from Vietnam
Just came accross your channel and really like it!
Thank you very much👍💪
This was really useful. Thanks!
Thanks for the explanation I have been taking classes at uni about this topic but my teacher hasn't been able to explained right. Thanks for the content. It was so helpful.
Thanks a million. This video is a life saver!♥
Thanks for the video man, really great explanation
"How about a 9 and a 1 and an 8" really got me smiling and singing it for the rest of the video!!
This man is a legend!!!!
Hello bro, just wanted to say congratulations on reaching 100,000 subscribers 😁
(I am glad I stumbled across this channel when I did, your tutorial playlists are the best on youtube)
Thank you Rew Rose! I remember you from early days of this channel lol
Thank you for sticking around since then!
@@BroCodez 😂 I've been working through my college courses, and only now did I start learning Java Spring.
(btw, your DS and algorithm videos have been very helpful so thank you and please continue the good work 😊)

Thanks man. This was awesome explanation.
CONGRATS ON REACHING 100K SUBS!!!! YOU ARE THE BEST, BRO!!!
Thank you Brucc! I owe you guys for getting me here!
Passing my GCSES with this one 🔥
🔥this guy video >>>> my 49$ DSA course
great tutorial! is there a reason we do j-- inside while loop and then use the [j+1] index instead of just removing the j-- and using the j index?
It's difficult but I have to try ,thank you!!!
This was what I was waiting for.
nice!
congrats for reaching 100k!!
Thank you Muhammad! I owe you guys for getting me here!
Cool video..please do videos on remaining sorting algorithms too.. like O(nlogn) in worst case...
Please never stop upload waiting for your complete course on data structures and algorithms
Thanks! I don't plan on stopping anytime soon 👍
Man you're a legend, no joke !
You are right dude
Thank you Engima! I will try and live up to that title!
Thanks, man

it's generally so overwhelming to do dsa but istg you made it so easy and the concept crystal clear😌👍

Yo bro, just wanna ask are you gonna drop C language videos anytime soon, wanna refresh my concepts of C that's all
I'm not sure when exactly, but I do plan on releasing C videos sometime in the future

Newbie here confused about
J - - dosn’t it set j to -1 after first loop?
Thanks for vid btw
j decreases by 1 during each iteration of the outer for-loop, then it stops at 0
👍
soo, bubble sort in reverse?
Gold
would this also be a valid solution:
private static void insertionSort(int[] array) {
for(int i=1; i < array.length ; i++){
int temp = i;
for(int j=0; j < i; j++){
if(temp
