How To Remove Duplicates From Sorted Array ( LeetCode 26 ) | FREE DSA Course in JAVA | Lecture 65

We are going to solve a Leetcode problem number 26 in which you have to write a program to remove duplicates from a sorted array.
So for a given sorted array like 2,3,3,4,4,6,6 you have to remove the duplicate elements and return the array in the form 2,3,4,6.
Now there is a simple brute-force approach to this program where you can use two variables and check linearly the duplicates.
But as a student of coding who is learning DSA, you must always look for an optimal solution that consumes the least time.
Let's see how we can more efficiently solve this program of removing duplicates from an array.

I HAVE NEVER SEEN ANYONE EXPLAIN LIKE THIS.❤

[@abdihaashin1350]

this is man is the best teacher. i never see before. my God bless you and your family aamiin

[@ManishJaiswal-sh3jm]

I have never come across such wonderful explanation video. Thankyou so much bro for the video 😊.

[@ahsankazi9837]

Brother thank you so much for taking your time to explain the logic , lots of you-tubers rush through to make their video short . Please upload more videos like this and explain it slowly. Thanks again, and GOD BLESS

[@shubhammanecr7]

Solution without temporary array is amazing!

[@newminds8619]

Beautifully explained sir👍

[@ankithareddy4497]

Just amazing explanation ❤ thanks alot

[@zainabalayande278]

I rarely comment on youtube videos, but I must say this video is superb and well explained. You made it really simple, most especially when you mentioned you needed two persons to go through the array...............thank you

[@SoniYadav-pe9hn]

your explanation is too good😍😍😍

[@bokinalavijay6876]

Excellant teaching sir thank you❤

[@prasadnakade8267]

Best Explaination Thank You Sir

[@Manishkumar-qy7zf]

Awesome explanation.

[@naidulipsa]

no one is explain like this thank you so much sir

[@shanmukhasridharreddypittu229]

Thank you bro you explanation is super

[@MohammedSameer-rx5rz]

Simply Awesome brother ---- My suggestion is Could you please teach with Real-life Examples taking Eggs, or any items to Explain Clearly for Better Understanding to students ... Thank you for your Teaching Style

[@jatin9987]

isme kya real life example chahiye bey

[@saarza9991]

​@@jatin9987 usko boiled egg pasand honge bhai don't judge

[@srin42]

Very nice explanation: This whole world of teaching is sucks.. and f ks.. naming variables with i and j 's but your naming variable's in meaningful manner which really helps alot for junior to senior. I bow you . Please keep doing many more. I will share my friends what's groups

[@TAPACADEMY]

Thanks for the appreciation.

thanks bhaiya for super explanation

nice explanation sir

Beutiful explaination

Amazing

[@posachowdamma7710]

sir super explantion

[@prajwalm.s7976]

Visualisation always helps

[@AestheticWorld_04]

Sir please tell me where you mention, that first element will be same as of previous array's first element in main code. Please tell me 😢

[@user-bl9ph5eg7z]

sir please upload more videos of dsa topics

[@BOSS55]

beautiful masterful glorious

[@guessme424]

amazing mannnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn

[@user-mg1my1zg7p]

Sir can we also provide Python code at the same time....concepts are clear but understaing the Java is bit difficult

[@ryanafzal4129]

What is time complexity of this algorithm?

[@user-bl9ph5eg7z]

please sir upload more topics

LeetCode must put your solutions in their Editorial section. Credit must be given to you.

sir 169ms runtime, is it good or bad ?

Sir this code is not submitting on leetcode, even when the Logic is 100% Correct and working Perfectly in VS Code

[@abhijithsuresh5334]

Sir question about Array Rotation

[@TAPACADEMY]

Coming up with this lecture today. Stay tuned

[@dipakbadgujar1238]

This will work for unsorted array?? And we can use hashmap for unsorted array

Personally I am suggesting student sir about u , really ur awesome the way u explain first meeting with u I will always remember re

[@aleefsultan176]

what about 234324?

[@babitakumari-ln1zb]

Edge cases not covered

[@codingcure788]

This is not feasible solution. Remove duplicates from array means it shouldn't be there. But still it is available inside array

[@khanra17]

It is the most optimal solution. It's inplace just slice till what you need.

[@codingcure788]

@@khanra17 brother suppose I will tell remove water from glass. Then what u will do ? U will empty the glass or still u will keep water ? U should remove all the water correct. Similarly here remove elements from array means the elements should remove permanently from array.

[@_sarthakmisal]

Cut the glass of required length lol ​@@codingcure788

[@SuvoBiswas-eh9sp]

Yes there are some problems in that method

[@SuvoBiswas-eh9sp]

public class Spiral { static void removeDuplicate(int[] arr){ int rd=0; for(int i=0; i

[@Timeless_Trader]

I am not getting correct output in case of below code: If anyone can help? What's wrong with this code? public class remDuplicates { static int removeDuplicate(int[] arr) { int rd = 0; for(int i=1; i

[@mdnouman5396]

bro this solution is only for sorted array you cant give input in unsorted order

[@mdnouman5396]

you can first sort the array and then send it to the function like these int[] arr = { -15, 1, 2, 3, 4, 5, 0, 3, 3, 1, 4 }; System.out.println(Arrays.toString(arr)); Arrays.sort(arr); // sorting int rd = removeDuplicate(arr); for(int i=0; i

[@Timeless_Trader]

@@mdnouman5396 Thank you for your help.

[@codingcure788]

Bro even you sorted the array. The output is will not come properly. Because remove elements mean it shouldn't be there.

u look like kl rahul
