Keep posting more videos bro
Bro I have a request to reply me regarding this doubt of mine , I want to start learning DSA in java .. now I'm initial stage of learning the language just introduced to some basic print function, conditional statements and loops... So my first question is what important concepts or till how much I need to learn like basics in java so that I can start doing DSA ... Secondly whose yt playlist is good for DSA / can you say if any free resources available in RUclips or any site where I can learn all the concepts of DSA
Dear, If u wanna solve DSA on any language, Ur command on that language should be very strong. Else u'll be feeling LeetCode DSA numericals to be very tough. So 've java very strong, from basics to inheritance, polymorphism, Collection classes etc..In a word, U should know everythings. For DSA theory, Jenny Mam (good concepts) on C, & for DSA with Java, might be I'm the best on free resources😇. 😂😂Joke!
@@farhaddubey ok bro then thanks for the recommendation, I'll try to have a strong hold on the language and then we'll start doing DSA
@@farhaddubey ok bro when I have to start DSA from scratch, from which of your videos should I watch ?
Wow amazing video, please make video in hindi
thanks
Wikigalaxy website is not open, how you are opened that.
great solution thank you!
❤
Bro keep doing
plz make videos around the basic intermediate ones
Ok sure, from Next Week
Awesome, difficult topic made easy 😊
🎉🎉🎉 very helpful
Wow amazing video ❤
Waiting for the next one , btw it was awesome 👍
Konse clg se ho aap name of ur clg ?
Keep ur hardwork
great explanation bro
Hi bhaiya pechana ?
yes! mere clg ka dost.
Good
you should've put your video on botton-right, the code is not visible
please make more such videos of js concepts...
amaizing!!!
Bro increase brightness of your room
