Using Sign Trick: int* ans; // ans[0]->repeating // ans[1]->missing for(int i=0;i 1 if(arr[x]repeating ans[1] = 0; //bit not set //->missing for(int i=0;i

Your XOR explanation is the best on youtube. I randomly chose to see this video on search results and now I am surprised by such a beautiful explanation.

I personally recommend your videos to all my coder friends as your ability of making people understand the solution is amazing

I found a highly underrated GEM You are way better than so called DSA-Gurus

Your channel is so underrated! Thanks for the alternate approaches, great explanation.

You explained the XOR one the best I saw on YT

Can you share mathematical approach like how should I code it ?? Btw amazing knowledge 👍🏻

Watching after tons of videos in this problem. Finally i understood this now . Thank you very much. And to be honest , you explained this much better than striver.

Love you Alisha, you are just the best. Literally nowhere on youtube could i find any clear solution. But you saved us.

Just came back to this video to say thank you for making this, approach 2 and 4 are my preferred ways of solving this and are perfect. Thanks for your help

In XOR, how can we sure that the diffrentiating bit will lead us to the answer. I have understood your point for putting the values in 2 different buckets accordingly but how diffrentiating bit is leading us to the solution 3^4 = 1 so what??

you're one of the rare person who solves code in C , thats really wonderful , looking forward to more of your videos

thank u i literally watched 2 times to catch your speed amazing work

Amazing explanation ma'am 👌👌😊👍

Thank you. ur explanation is awesome

Xor explaining is awesome

how can we get multiple approaches with any problem ???? Unbelievable 🙌🙌🙌😵

Exception Explanation 🔥

Thank you so much.

u deserve 100k subscribers

This is most Underated Channel

sign trick in Approach 3 is wowww!

You are too good 😍

Didn't get the intuition behind xor approach

😊 thanks ma'am

Thank you alisha👍🏽

Damn good yrr... 👍

The video is nice but I suggest that you avoid repeating same line multiple times. For e.g "xor of 2 and 3 is 1" you have repeated this thrice ....this makes the video unnecessarily long

Thanks a lot maam

Thanks diii

👌👌👌

striver really confuses a lot

I hate Math solution's so damn much. They are so unintuitive to come up with during an interview especially if you never seen this problem before. I'm gonna stick to the counts tracker solution and the sign trick solution, thank you

You are a metallurgical engineering ,then how are so proficient in coding,huh?

Top notch explanation💯🔥
