LeetCode 53 | Maximum Subarray Solution (Kadane's Algorithm) Visually Explained | Top Interview 150
Welcome to a clear and concise walkthrough of #LeetCode 53: Maximum Subarray, a cornerstone problem from the Top Interview 150 list! 🚀
In this video, we skip over complex and unnecessary methods and dive straight into the most efficient solution using Kadane's Algorithm, which runs in O(n) time complexity and uses O(1) space complexity.
✅ What you'll learn:
Quick and intuitive explanation of the problem:
We'll discuss how the task is to find the contiguous subarray with the largest sum, and why brute force solutions (checking all subarrays) are inefficient.
The optimized solution step-by-step:
Learn how Kadane's Algorithm works by iteratively maintaining the maximum sum so far and the current sum for the subarray.
Code walkthrough:
We'll break down the Python implementation of Kadane’s Algorithm, which can easily be adapted to any programming language of your choice.

    • @Byte_Quest

      That's how the KMP Algorithm is designed. 5 to 13 is a match and 10 to 18 as well. Those two matches are overlapping, that's why KMP started matching from 13 directly (because it already knows that from 10 to 13 is matching)

      We're doing "Union by rank" so no need. If we were doing Union by weight we would have further increased. You can modify your code and make it like that.

  • @BlyatifulButter
    @BlyatifulButter 9 днів тому

    Excellent explanation! Although, I must say using `l` instead of `j` for the prefix-suffix array part was quite confusing at first. Like when `lps[i]` gets updated to `l` when `pattern[i] == pattern[l]`, I thought it was being updated to the value 1 and was confused lol But the visuals helped me understand the KMP algorithm on a deeper level, and that's all that matters, so thank you!

    • @Byte_Quest
      @Byte_Quest 9 днів тому

      Aha, yes while creating the LPS array.

  • @sozkaya
    @sozkaya 10 днів тому

    The problem with all these KMP videos is , they are all jumping from naive approach directly to a pattern of suffix==prefix matching ( abc...abc ). What if the pattern is "abcde" ? Which I think is the most crucial part of the algo.

    • @Byte_Quest
      @Byte_Quest 10 днів тому

      Hey, that's an excellent question. Worth pinning. You provided the pattern:- "abcde" So the LPS array will be: [0,0,0,0,0]. Now keep in mind that i always move forward (no backtracking). When the current j (pattern letter) matches the current i (text letter) they both get incremented by 1. And when they mismatch and j is 0, i get an increment by 1 and if j is not zero, it will go to the target index found using the LPS table. Now the key idea is that i always move forward. Hence the overall complexity remains linear.

    Can you please explain how you came to the bruteforce time complexity of O((n - m + 1) * m / 2) specifically the m / 2 part. I understand the n - m + 1 part since we are not looping the full string. I am not able to understand the m / 2 part. Unless we are doing some optimisation to reduce the pattern searching by half which is not possible/ we are not doing in bruteforce. You have mentioned: On average, it compares m / 2 characters which I don't think is the case or even if it is the case, we don't give time complexity considering average cases or best cases. We give it according to worst cases. So at the end, the time complexity would come to O((n - m + 1) * m) which we can say as O(n * m).

    • @Byte_Quest
      @Byte_Quest 16 днів тому

      The pattern will go over the text n - m + 1 times, In each iteration, while matching the corresponding letters, if any letter didn't match we break the inner loop without checking further letters.... So sometimes the matching runs nearly as long as the pattern length and sometimes it breaks earlier... So we conclude that half the letters are matching on an average.

  • @drunkbox2726
    @drunkbox2726 26 днів тому

    I have a doubt. For example, A is the sender, B is the receiver, and C is a hacker. A encrypts the text (e.g., "I am Ashwin") using B's public key. Is there a chance that C (the hacker) could modify the text (e.g., to "I am Vinoth") using the same public key of B? If so, when B decrypts the message using B's private key, they would get the text "I am Vinoth" instead of "I am Ashwin." In this case, C (the hacker) cannot see the original message sent by A but has modified the message that was sent by A.

    • @Byte_Quest
      @Byte_Quest 26 днів тому

      C can intercept and replace the original message by encrypting a new message (e.g., "I am Vinoth") using B's public key. However, C cannot read the original message sent by A or impersonate A authentically without A's private key. To prevent such attacks, A can use a digital signature to sign the message before encrypting it. This ensures that B can verify the message's authenticity and detect any tampering. Secure protocols like TLS/SSL can also protect the communication from interception. C cannot directly modify the message that has been encrypted by A. It would lead to dara corruption.
