Thank you so much for that course. I really enjoy watching it. I watched a lots of your solutions to leetcode problems, but sometimes I don't have any idea whats going on. I think this series will help me understand more about algorithms. Thank you Greg 🙂
At 15:06, modifying an index in a string takes O(n) and not O(1) as it creates a copy of the initial string first and then modifies that particular index. Btw, really loving AlgoMap and your videos. Great work!
1. He's talking about an array at 15:06, not a string. 2. Before getting to that point he already said that strings are immutable, and that most operations (including appending or modifying an index) are O(n) for them.
Hi Greg Thank you for the course, I really enjoyed it , I just want to ask if you can post a video where you talk about your career path from high school to what you've reached now . Warm greetings from Morocco
I finished python basics ,functional and oop after this course can I start solve problems in leetcode and can please make vide for machine learning roadmap with resources please and thank U ❤️
Hey Greg! You can append an element in a string like.. s = "hello" s += "z" print(s) we didn't make a new variable but just added "z" in s. Correct me if I'm wrong
If you know the index of the element you want to delete, you can use the ''del'' statement. Or you can use pop() which removes and returns the removed value, And if you know the value to delete and not the index then you can use remove()

Sorry for the slow reply, really glad you've been enjoying it!
Keep this playlist going brother . Really very healpful for all python students . Keep It up.
Will do!
Day 3 of being consistent to the DSA playlist
One month later. Did you master it?

This is the kind of course I am would be ready for pay for ❤ 😅
Please continue this series we need more
Haha luckily it's free!
@@GregHogg Lucky me 🤞 🤞
Thank you so much bro! I'm following from IG to here. :>>
@GregHogg I really like the way you explain the concepts, it will be more useful if you do lectures on Java too. I hope your java lectures in future .
@GregHogg - U didn't cover ArrayList concept in this DSA course as it is important in dymanic array right?
i'm from India now i can say you can defeat the Indian teacher , but this is my first video and loved it .
😍😇👌👍
Loving the series. Thanks!
Glad to hear it!
Nice one looking forward to more vd's🙄
Thank you!!
Python continues to be the awesome :B
Hi Greg

Warm greetings from Morocco
I finished python basics ,functional and oop after this course can I start solve problems in leetcode and can please make vide for machine learning roadmap with resources please and thank U ❤️
What took are you using for all the scetching if you dont mind me asking . Thanks for the amazing videosb
Miro :)
guys can anyone say what is the type of whiteboard that he uses please?
Hi Greg, could please make a video to explain how these concepts "hashing, __eq__ method, and immutability" work together under hood?
Yep working on it haha
To get 5 from array we can use binary search which will give nlogn time will that be good idea over 5 in arr??
Yes you can use binary search in log time if it's sorted
@@GregHogg thanks and I get your LinkedIn sir want to be in your connection
Is this for beginners
Hey Greg! You can append an element in a string like..
s = "hello"
s += "z"
print(s)
we didn't make a new variable but just added "z" in s. Correct me if I'm wrong
Well that doesn't really append it still makes a copy and adds the letter but the syntax is quick yes
How to delete an element not at the end in array?
If you know the index of the element you want to delete, you can use the ''del'' statement. Or you can use pop() which removes and returns the removed value, And if you know the value to delete and not the index then you can use remove()
@Ak-ggs, you are right and remember @rajeshkannan8608, deleting an element that's not at the end is an O(n) operation.
𝘾𝙖𝙣 you give me data structure roadmap with example which I have to solve
Check out my full 100 video playlist=
Didn't understand a thing 😅
I watched the video, but I can't solve a single leetcode problem on the algomap regarding lists and string, am I done? :(
It takes practice give it time homie
