Wow! Been learning your beginner programming course but stopped because I can't follow on the big o notation part and been searching to learn more about it. You posted about it when I exactly needed it, thank you so much ! You guys are such a lifesaver!
Simply amazing visualizations! A great teacher is able to break down complex topics, and visualize them intuitively, summarizing without removing any of the details, indeed making the details easier to understand.

Thank you for clearing the Big O notation concept in this video. I searched everywhere to learn that concept but didn't find any. So, when I came to know about this video, I'm extremely proud of myself for choosing this one. It has cleared all my concepts related to Big O and space complexity.
1:15:30 - (i) Actually in the merge function (helper for mergeSort), you can exit the while loop earlier, instead of using &&, you can use || (OR) instead because you are presuming to use two sorted arrays as the function arguments anyway (otherwise, the two-way merge will not work). What that means is, if any one of these arrays are already part of the final merged Array (i.e. we have traversed through at least one of the two arrays, that means we can simply concat the other array which still has elements not added to the merged Array, to the end of it, without any further thought). (ii) The concat method can be used like this instead of two concats. ``` const merge = (arr1, arr2) => { let i = 0; let j = 0; const mergedArr = []; while (i < arr1.length || j < arr2.length) { if (arr1[i] < arr2[j]) mergedArr.push(arr1[i++]); else mergedArr.push(arr2[j++]); } return mergedArr.concat(arr1.slice(i), arr2.slice(j)); }; ```
3 years and this is still ridiculously helpful! This video is a guide on how youtube videos should be executed, that no matter the age the video is still relevant
At 1:05:40, you don't need to specify the last element of an array in the slice function. Leaving the second argument blank will do the trick, as specifying only one argument in slice goes to the end of an array by default.
EDIT: n^2 means n squared. Here is a better explanation for O(n^2) for anyone who didn't understand the one in the video. For loop is a O(n) operation. A for loop inside a for loop is also a O(n) operation. The inner loop iterates as many times as the other loop iterates, so n*n, which is O(n*n). And n*n = n^2. EDIT 2: n^3 is just n*n*n
Throughout the Covid-19 pandemic businesses and Government faced the need to solve multiple,competing priorities simultaneously.

Since Cryptocoins can be traded both inside and outside the digital currency environment,digital currencies are more than jst a way to pay for goods and services-they’re also a viable investment opportunity. in fact,Cryptocurrency has several advantages over fiat funds when it comes to investment opportunities,one of the biggest is that it isn’t subject to the same market conditions that traditional currncies are when it comes to foreign exchange rates. The best example of this is the state of the pound after the UK voted to leave the European Union. in the wake of the Brexit vote,the value of GBP began to plummet as investors responded to the realities of the UK leaving the EU and the financial instability this new situation created.However,the world of digital currency is insulated from such real world issues thanks to its very nature -its not tied to any single bank or government. in some cases,Cryptocoin value actually increased as investors realized that digital currencies like Bitcoin were unaffected by Brexit.Another important advantage of cryptocurrency is its potential for explosive growth.Bitcoin,for example,has demonstrated overall positive growth since its inception-as of August 1st,2017,Bitcoin was trading at more than $2500 per coin,whereas a year ago it was trading at around $600 per coin.Industry experts have long predicted that Bitcoin can and will increase its value even higher in the future,providing excellent potential for long-term growth.

We've seen these dip many times in the last 10 years, cannot believe people still get scared with these healthy dips, Buy the discounts! Christiana has always been good at analysing this
Insightful content, Well personally I feel, those who would allow the market dynamism determine when to trade or not are either new in crypto currency world in general or probably just naive, crypto currencies have seen far worse times than this, enlightened traders continue to make good use of the dip and pump even acquiring more equities towards trading sessions, months back I started trading, though i knew just the basics of trading, i wasnt able to capture the secret to understanding the use of signals till I got connected to trading Expert Christiana Robert . Under her guide I've been able to understand the market structure and how best to use signals for amazing returns, plus her trading classes has been so educative,
I've looked at so many videos trying to find a person who explained it easiest and quickly and somehow the nearly 2 hour long video is the only one that did both of those

I tried books, articles and other videos that tried to explain Big O Notation and all of them left me more confused and frustrated after seeing them than before I started. As all the other commentators have said, "Well done". A brilliantly simple visual and clear explanation. You are a great teacher! 😃👍 I understand it now but I will watch this again a few times to get the code examples in my brain.
This is pure gold 🤩 thanks for making such amazing content. Initial i did not expect to stay till end of the video but boy oo boy the content quality is so good that it kept me hooked. Love you guys 🤩
Great explanations and examples with good drawings. It is highly under appreciated when you take the time and effort to make your handwriting legible and use a consistent color pattern when explaining examples. This really makes a big difference visually in understanding the parts. Thank you so very much!
Step by step explanations made me to understand Time complexity much better than many other UA-cam tutorials. Kindly feedback, why space complexity not explained much ?
1:20:13 actually thought that was my stomach while in the library and looked to see if I had disturbed people! great video, awesome you should lecture at my Uni way more students would get you than the lecturer!👍
Wow! Been learning your beginner programming course but stopped because I can't follow on the big o notation part and been searching to learn more about it. You posted about it when I exactly needed it, thank you so much ! You guys are such a lifesaver!
Dutch! You better to have a Plan.
Quite possibly the best explanation of Big O that I have come across on the web period!
You dont know how much i wanted this course
thank you so much Free Code Camp
you really deserve a lot of praise

This channel is killing it it's like Top 1% of the content Thank you so much
the sound at 1:20:12 it got me cracking up lol.
an amazing straightforward tutorial, thanks a lot!
just experienced it also!
My man's hungry lol. Need some break :)
Two hours well spent!!!
Amazing course, Clear and Concise Explanation of each topic. Thank you so much for making this video.
That is the best explanation about Big O notation I have ever seen 🤯

const merge = (arr1, arr2) => {
let i = 0;
let j = 0;
const mergedArr = [];
while (i < arr1.length || j < arr2.length) {
if (arr1[i] < arr2[j]) mergedArr.push(arr1[i++]);
else mergedArr.push(arr2[j++]);
}
return mergedArr.concat(arr1.slice(i), arr2.slice(j));
};
```
If you use OR you can get out of range for one of the arrays.
What language are you using ?

The hand drawing behind the screen doesn't help with that! Please stop using that it's distracting af!

I’m curious about what made you think this was a better explanation. To me, it’s just another explanation.
@@samuelodan2376 A different perspective can be a much better perspective depending on the person observing it.
@@BusinessWolf1 hmmm 🤔
Didn't see it this way till now
Thanks ☺️👍
@@BusinessWolf1 that means there’s potential for it to be a better explanation, not that it already is, right?
could you explain the log one? to me it amounted to "it's log because it's log, now you understand!"
This is the best Big O Notation video I have ever seen.
Those "Big O notation in 10mins" videos were NOT cutting it for me. Thank you soo much!
You make it so easy, best channel in UA-cam man
Trust me this is the best video for understanding O notation I have ever watched.
One of the videos with a high quality explanation.

This is the best big o notation course. Everything is explained very well. Thanks.
Best course for big O notation ever
I've looked at so many videos trying to find a person who explained it easiest and quickly and somehow the nearly 2 hour long video is the only one that did both of those
Studying for my computer science midterm. Great video helped me a lot!
Studying this for my national Olympiad ☠
Thanks!
This is gold, you made Big O easy to understand
This is the best video on time complexity on UA-cam, period. 😀
Thanks!
This is the one video that finally helped me to understand big O
well, this video achieved what a degree and other courses couldn't. thankyou :-)
the best O notation tutorial !!!!!!!!!!!!
best 2 hours i have spent on any course at all now i can say i understand the Big O notation
Must say that thats the best tutorial related to the subject!!!
I have seen a lot of different stuff but this one is the best! 2 hours well invested. Bravo and thank you for these crystal clear explanations!
THANK YOU.
been wanting a video on this for a while
This is the most amazing tutorial on big o notation! Thank you!
i have been struggling so much on understanding this topic, and this video discussed it at the perfect pace! thank you!
the 0(log n ) example at 30:34 cause a stack overflow. the correct way to implement. function log(n) {
if (n
Video is good because of the content and the implementation in javascript makes it even better.
sir you have a potential to become a great tutor
- the way you break down a complex topics into a simple one.
- Clean visualization .
- Detailed explanation.
keep it up the great work

Great explanation! So far this has been the easiest out of my 3 days of journey in just understanding the meaning of big o notation
This is the best video i have found so far for understanding big O notations! Thank you.
Wish I had this source available 3 yrs ago. This is taught so well I had to watch it!
wow! i'm so blessed, thanks for the course i now understand what Big O notation is!
Nothing was glossed over. Everything was explained so well. Great job man!!
🐐🐐🐐Amazing video, don’t hesitate to make more
Best explaining I have seen

Best course i ever watched ! simple to understand🤗
Long time awaited!
First time I really understand what is Big O notation !!! as a CS student
This is a clear explanation of Big O.
Thank you
This video ease up my brain on Big O notation. The video is good. Thank you.
You are a really good teacher!!! many thanks!!!
This is pure gold 🤩 thanks for making such amazing content. Initial i did not expect to stay till end of the video but boy oo boy the content quality is so good that it kept me hooked.
Love you guys 🤩
Thank you very much Giorgio thompson! Easily the best video explaining big 0 notation in my opinion
Awesome tutorial !!!
the thumbnail was sick !!!!
I wish Such kinds of youtube courses were available during my college days. But till now my learning appetite is increasing exponentially.
Great explanations and examples with good drawings. It is highly under appreciated when you take the time and effort to make your handwriting legible and use a consistent color pattern when explaining examples. This really makes a big difference visually in understanding the parts. Thank you so very much!
Best explanation for time complexity calculation. Thanks!
Awesome video that really helped me to learn Big O and understand it better. Thank you selikpro!!
I am really becoming a great fan of this coding camp
Step by step explanations made me to understand Time complexity much better than many other UA-cam tutorials. Kindly feedback, why space complexity not explained much ?
thanks,just love for your work and collabs!
Thanks for the video, greetings from Argentina!
This is what I was waiting for. Thank you.
OMG i'm studying it on school and u guys help me so much
Thanks for the lecture! I now have a good grasp on this topic.
WOW THANK YOU SO MUCH, Time complexity is so easy to understand now!
And that, ladies and gentlemen, is how you teach Big O. Thanks!
Insanely simple and precise
This guy really did a great job... Thanks so much for this
at [1:15:00] we could return this in python -- > ""return result + [left_arr[lx]] if lx < rx else result + [right_arr[rx]]"
dropping right videos right during interview season. great!!!!
Wow! Amazing explanation.
YES finally something about my favourite topic!
Thank you so much! This video is definitely a teaching masterclass. Great stuff!
What a great explaination. Thanks a lot man. Im loving it.
I don't care whatever it is. I love keep watching this because this is interesting.
Teaching is great.
Very good and clear explanation, sorted many of the questions I had in mind. Thanks.
1:20:13 actually thought that was my stomach while in the library and looked to see if I had disturbed people! great video, awesome you should lecture at my Uni way more students would get you than the lecturer!👍
Thought it was my stomach too 😂
great video , love from india
Such a nice guy and i loved this tutorial so much , it's so different
Thank you so much for this video! Desperately needed it!
Thanks for this good course.
Been up since 5am… it 10pm and i just found this, i have to watch it now… wish me luck.
Thanks for the in depth explanation
Fantastic course, with amazing examples. Simple objective, now I can study better algorithms. Thank you very much!
Thank you and watched the full video.
I only know python and still understanding his code 100%.
Thats what good teacher matters
Thanks for the wonderful explanation!
Such a precise description of each time complexity and well organized. Ty so much!
Nice. The illustrations made understanding the big-O concept very easy. Thank you.
What a tactile video lol, the keystrokes added a strange ASMR element to the learning experience :p Didn't know I was into it until now!
Man seriously I was thinking about this today only that how hard it is and your came like a magic
Great video. Thanks! Took awhile but well worth it.
