Subsets | Simple Story To Code | Leetcode 78 | Recursion Concepts And Questions | Video 17 

Did it on my own 🥳 all because of your past teachings Thank u so much💖

came here to learn about subsets

solved today problem of the day!

Thank you so much mik. I wanted to let you know, me and my friends are learning from your playlists and we play it on speaker and everyone sits and listen and make notes. Thank you so much again for doing so much for us.

bro ur explanation is the best

bhai tera lakh lakha dhanywaad 13:49 pai jo chij thi vohi samazne ki kab se koshish kar raha tha

class Solution { public: vector subsets(vector& nums) { int n=nums.size(); vectorv; int subsetsum=1

Your consistency is on another level.

Exceptional Teaching ❤❤

Never stopppp working sir❤❤❤we are greatfull to have you

Additionally, I enjoy watching your videos. They provide really good explanations. Thanks a lot for your efforts.

Best thing i Got this year❤

i request you to complete the series ,dont put this on hold or stop the series. Amazing video as always

sir ek code ka dry run bhi kraa dete to or achay say smjh aata..btw thank you 💯👍

Similar aayega to ek set bna lenge aur last me phir set ko vector me convert kar do that is the approach

//ye bhi ho gaya khudse beacause of you class Solution { public: void backtrack(int idx, int n, vector& temp, vector& ans, vector& nums){ if(idx >= n){ return; } temp.push_back(nums[idx]); ans.push_back(temp); backtrack(idx+1, n, temp, ans, nums); temp.pop_back(); backtrack(idx+1, n, temp, ans, nums); } vector subsets(vector& nums) { int n = nums.size(); vector ans; vector temp; ans.push_back(temp); backtrack(0, n, temp, ans, nums); return ans; } };

bro keep making video like this

upload the video for duplicate elements also sir helpful for us

Thanks a lot bhaiya ❤❤

How to do this with for loop method?

maza aagya yrr

Sir, why here temp.pop_back() is not given after the second recursive call? but given in 'generate paranthesis' question? When I removed the second pop back from generate paranthesis qn , it is not working. what is the difference between these two?

What you did for not selecting a duplicate subset ? I m confused

Sir please make of today's GFG potd

one error temp.add(nums[i]);

I m here to watch your videos but disappointed because language is Hindi😢

code for duplicate. public Listsubset WithDup(int[]nums){ Listans=new ArrayList(); Arrays.sort(nums); backtrack(0,ans,new ArrayList(),nums); return ans; } private void backtrack(int idx,Listans,Listtemp,int[]nums){ ans.add(new ArrayList(temp)); for(int i=idx;i0&&nums[i]==nums[i-1]) continue; backtrack(i+1,ans,temp,nums); temp.remove(temp.size()-1); } } 🎉❤
