Hey Striver, First of all Happy New Year I want to say if possible please try to make 2 videos of DSA in one week. If possible Thank you for this course
Happiest New Year Striver!! I eagerly wanted to contribute to python codes for TUF articles. I even sent a testimony by writing a sample code on takeuforward111 but have not heard back yet. Do consider it!
Today is 4 JANUARY, 2025, i have started my journey with Strivers SDE sheet, i will come here periodically to update my status and my offers! Wish me luck!

I don't know whether you will see my message or not but it's such a great time to be alive when we are getting to see Striver. Thankyou soo much. I wish i will get to see you one day. #StriversA2ZDSA *Understood* ♥️🔥
Time Complexity is Rate at which the time taken increases with respect to input size. Time Complexity is calculated in BigO notation. 3 rules for calculating TC: Calculate with worst case scenario. Avoid Constants Avoid Lower Values BigO-worst scenario Theta-average case scenario Omega- Best Case Scenario Space Complexity: SC is also calculated in BigO notation itself There are two spaces. 1.Auxilalry Space:The space taken to solve problem and store solution. 2.Input Space:The space taken to store the inputs. C=a+b Where C is auxillary Space. a and b are input space. While coding, tampering the input for SC is wrong practice.
Every time, when i started studying about DSA, i felt bored or frustrated, but this time by watch your video lecture, i didn't feel that way, instead i felt motivated to continue on this course, Thanks man i really grateful to you
understood. i have tried different platfdorms to learn DSA but you are the only one i am continuing and getting concepts crystal clear... Thank You Striver!
i am starting my DSA journey at 22/01/25, i will daily come here and upload my status of completion. Thank you striver for your valuable effort Day 1 complete
Today I am getting started with the playlist. I have 12+ exp already and now learning DSA to enter into my dream company. I regret the wasted years but I hope I am not too old to start now. All the best to everyone❤
Bro Can I learn this DSA for solving problems and improve critical thinking not for interview purpose Ofcourse I'll face that rather than that is this good ???
Understood. Today is November 18th, 2024, i have started my journey with Strivers SDE sheet, i will come here periodically to update my status and my offers! Wish me luck!
@ Hey, I have watched starting ke 8-10 videos and then I got busy giving interviews. But now I’m back on track again and watching regularly. You tell me, how’s your progress been brother?
"Wow, I finally understand the concept of Time Complexity! Your explanation was clear and concise, making it so much easier to grasp. You're a superb teacher, and I really appreciate your ability to break down complex things and make them understandable. Thank you for sharing your knowledge and helping me expand my understanding. Keep up the excellent work!"
He most probably made this video some days or weeks ago .... and his editor or he might just put it out today.. Ofcourse he's not gonna waste 31st like this 🤣
@@souvikghosh5768 bro I'm talking about students who are watching videos right now or first January 🙂 I know very well video can be scheduled as well in youtube when it will be released 🙂 Happy new year bro 💫
This has to be the best explanation for time complexity on TH-cam. I couldn't understand what my lecturer explained and other youtubers also but your explanation i understood in the first explanation itself. Thank you so much for this brilliant content.
Thank you, Raj, for explaining the concepts in detail. Although the topic was not naive to me listening to it still gave me info that I was not aware of. I am liking the way you are explaining the concepts and helping the community to understand DSA properly.
Today is 25 July, 2024 and I am starting Striver's A-Z DSA playlist. Will comeback here periodically to update my progress and let you all know about the offers that I get. Wishing you all lots of luck!
@@bibek31566 oh, that's great to hear! I'm doing well and staying consistent. I wish you the same for your future endeavors!. When Delving deeper into a subject often reveals interesting details.
Hey did u checked the take u frwd website and A-Z sheet there ? I'm confused that in that sheet , there is search query auto complete prblm is there in practise for input/output topic....how can this difficult prblm could place under this simple io topic..did u solved ?
STRIVER I recently completed your DP series it's amazing and i understand well and good .. But in this video you look so handsome as your explanation.. Happy new year keep glowing and make everyone glow with your content......
Today is November 16th, 2024, i have started my journey towards DSA using Strivers SDE sheet, i will come here periodically to update my status and my offers! Wish me luck!
I am a final year student literally i tried underdstanding time and space complexity since 3 years refering all top youtube channels but did'nt got this much of explaination as i got here , tq so much for your explaination sir , we are blessed to have you , i hope i will cover all your videos . Tq so much sir once again
Started this video playlist just like every other tutorial video to be left in middle . But brother the way you explain is just too good . Will make me stick till the end. Thank you for the efforts. 💪
understood im starting to gain some confidence after step 1.1 i hope i will surely come back one day to leave a msg saying i creaked a coding round and got placed bcoz of you and i have that confidence till that im going to work hard with you ans my mentor thxs striver 🥰🙂🙂
Today is 6 Aug 2024 ,I have started this Striver's A2Z DSA Course .Wish good luck to all who have started this journey and hope you all accomplish your dreams. 😊
I'm in Service Based Company after completing my graduation in BCA. As in tier-3 colleges, professors & faculties don't teach in deep and instead focus on syllabus. Inke syllabus ko bhi update huye almost 8-9 years ho chuke hai. But still managed to crack a job in top MNC by myself in 2023. It's almost 1 year after joining and learned lots of new skills, and still facing challenges in solving complex problems..Kyuki DSA college walon ne sikhayi nahi and khud se jitni sikhi utni kaafi nahi thi. So, as a new year resolution I'm starting learning Advance DSA from today i.e. 12/01/2025. 🙌
happy new year to you too bhaiya.....just one request please keep uploading videos for a2z dsa course MORE Frequently because if break is too long between videos then it affects consistency and we end up leaving course in mid way so hope we will see videos more frequently from now !
awesome 🔥 just a suggestion. keep the facecam video pinned in right/left bottom corner and the screen behind that on entire screen. that way, the video will look a lot more neat and engaging also. Thanks
We don’t wanna stretch the ipad screen reso too much unnecessarily. We will have it like this only. It has worked well for us in dp, graphs. Post experimenting, we have found this to be more engaging and to have more screen presence
Its 11 january, I am starting your course. I promised to give my all efforts in next 4 months to end this course..... I will make sure, I will come and update here
Today is 24 august and I am starting my dsa journey today.I am currently studying final year.I have just 6 months to learn dsa completely.please all of you wish me for best.And suggest me to get placed in a good company 😊
understand : summary:: time complexity- the rate of time taken increases with size space complexity - no of variable or you can say the size units you take during the code and it's of two types auxiliary and input space complexity
Let's march ahead, and create an unmatchable DSA course! ❤️
Happy new year everyone, wish you loads of success in your life :)
thank you sir giving everyone this magnetic course ,solute to you 🥰🥰
happy new year and thanks for this amazing content.
Hey Striver, First of all Happy New Year
I want to say if possible please try to make 2 videos of DSA in one week.

*Understood* ♥️🔥
Where can I get 0:06 that DSA Sheet of Striver's ? Link ? Or site's name ?
Time Complexity is Rate at which the time taken increases with respect to input size.
Time Complexity is calculated in BigO notation.
3 rules for calculating TC:
Calculate with worst case scenario.
Avoid Constants
Avoid Lower Values
BigO-worst scenario
Theta-average case scenario
Omega- Best Case Scenario
Space Complexity:
SC is also calculated in BigO notation itself
There are two spaces.
1.Auxilalry Space:The space taken to solve problem and store solution.
2.Input Space:The space taken to store the inputs.
C=a+b
Where C is auxillary Space.
a and b are input space.
While coding, tampering the input for SC is wrong practice.
input space is space taken to store the input

understood .. thanks for making it easier to understand
Completely Understood ❣
Thanks a lot Raj Bhaiya. Understood everything and doing good.
Understood clearly.
understand :
summary::
time complexity- the rate of time taken increases with size
space complexity - no of variable or you can say the size units you take during the code and it's of two types auxiliary and input space complexity
happy to here to learn amazing technique
Understood and really concise
lets go will complete these playlist along with sem 1
directly to the brain sir ,understood sir ❤❤
you are the best brother😍😍
understood !!!
You are the best man!!
