subah se pareshan tha. I watched Larry's video but kuch samajh nahi aya. Finally I understood each and every point. thanks a lot . I will also say -> NETFLIX ❌ MIK Lengthy video 💚
I can see the hard work in this video. There were few videos only for this problem on UA-cam which i tried watching in the morning. They wasted my time. And this legend makes a video of 1 hour to clear all my doubts . Guruji 🙏🏻🙏🏻🙏🏻 aap kamaal ho
I love your explanations! The way you slowly build up intuition from examples really helps. Most other videos just go over the top solutions, without getting into the intuition, which may lead to memorizing solutions.
For the first time, I could solve a Hard question in 15 minutes myself. And like you said, it was only possible because I had solved a similar question before. In the biweekly, there was a similar question where k was fixed = 3. I figured it out during the contest that it's greedy approach. Even in this question, I instantly knew it was greedy. Now, to tackle with variable "k" , I had solved a similar question using "Scanline Algorithm" and instantly I knew how to tackle with "k" . The final solution consisted of combining these two, and I had already solved similar questions before, this hard became literally easy-medium.
Enjoyed learning the intuition of this problem a lot and the best part is that all the three approaches were beautifully connected, now this hard level prob also feels like a cakewalk!! thanks a lot!!
Oohh thanks a lot for such a clear explanation.....❤ ignore the people who all are saying vdo is lengthy....if they got the concept at the starting they can even do it by themselves rather then complaining
Bro your contribution is amazing! matlab ye video recording he 1 Hr ka hai to preparation aur apko samajhane me kitna samay aur efforts lage hoge. Hats Bro!! 🗿
No one on this UA-cam platform , i understand this problem from them but after seeing this video of MIK Bhaiya it is in very interesting way he solved that and I learnt from him
Jeetu Bhaiya from Kota Factory == MIK Bhaiya from DSA Industry ❤️❤️ Thank you so much bhaiya itna time leke itna easily samjhane k liye ❤️ And those who are saying why 1 hour long video, guys please understand it is impossible for bhaiya to explain in this much details with multiple dry runs within 15-20 mins. If you don't have time to watch a 1 hour long video and want to solve a leetcode hard problem just for the sake of maintaining a streak then don't do it . Belive me 1 hour deke dekho regret nahi karoge 😊💯

Hi MIK, I have a doubt regarding approach 3. Why we have used deque instead of queue. Is there any particular reason for using deque because both enqueue and dequeue operations in both queue and deque take same time O(1)..
Bhaiya, Approach-2 mai aapne nums ko hii modify kiya hai, toh vo bhi toh space complexity mai count hona chahiye naa ? isFlipped nhi liya lekin data tamper kiya hai, toh space used should also be O(n) in approach-2
bro i am following you for very long time , but one suggestion of mine is don't make too much large video you can explain the logic by one good testcase . We can not spent 1 hrs for one question so please try to make it as short as you can .

Tried other UA-camrs videos on this topic, couldn't understand, here you cleared everything

I believe no one has the patience to cover even every minute points in the explanation . Hats off to you
Watched till 25:15 , then i was able to do it by my own. Thanks for helping me building the intuition.
*Javascript Code:*
var minKBitFlips = function(nums, k) {
let res = 0;
let currFlipCount = 0;
for(let i=0;i=0 && nums[i-k]===-1) {
currFlipCount--;
}
if((currFlipCount%2===0 && nums[i]===0) || (currFlipCount%2===1 && nums[i]===1)) {
if(i+k>nums.length) return -1;
nums[i] = -1;
currFlipCount++;
res++;
}
}
return res;
};
Excellent explanation of how to use the isFlipped array bhaiya!!! Thanks... I was stuck on this question for a long time!! Please keep uploading
very very nice explanation than all others whom i warched this. thanks keep it up

bhai tumhara ye comment instagram and linkedIn me kaafi reach me ja raha hai. MIK posted about this comment 👍
great explanation
we can also use if( (nums[i] + flipcnt ) % 2 == 0) then we will flip
Kya baat hai sir, sochraha hu apna bhi ek channel khol lun, padhane se khud ko bhi zyda smjh ata hoga… aap Konsi company mei ho?
love u guruji!
i made it myself thankfulllyyyy!!!
Hats off bhai🫡
Bhaiya *longest valid parantheses* important q h please video banaiye aapne bola tha ki weekend par banaunga
bhai ho sake to brute force bhi explain kiya kro taki jo new log h logic banane ka try kr rhe h unko bhi samjh aye chize acche se.

Kya ye ques hard tha ...No is video ke baad , not at all , it was super easy....
Hi MIK, I have a doubt regarding approach 3. Why we have used deque instead of queue. Is there any particular reason for using deque because both enqueue and dequeue operations in both queue and deque take same time O(1)..
Thanks mik, for such a detailed video, can you also pls discuss the solution for leetcode 3192.
bhaiya please provide slides in all the next question please
Insane explanation 😳🔥
And 38:13 was awesome 🙌
Great explanation
Bhaiya, Approach-2 mai aapne nums ko hii modify kiya hai, toh vo bhi toh space complexity mai count hona chahiye naa ? isFlipped nhi liya lekin data tamper kiya hai, toh space used should also be O(n) in approach-2
Bor bit manipulation playlist pls😎🙏
Minimum Operations to Make Binary Array Elements Equal to One II , can we solve this with same approach ??
Sir, everything was good but please make a length video shorter.

else nums[temp] = 0;

No need to create toggle function.
For toggling use:
nums[i] = 1 - nums[i]
it is modified problem of leetcode 3191&3192?🎉❤
