    Great Tutorial. Just want to add one thing. In bubble sort you can reduce the number of iterations of outer loop one time. It will perfectly work fine and will make the code more efficient.
    public static int [] BubbleSort (int [] arr){
    int len = arr.length;
    int temp =0;
    for(int i=0;i

    I found a small mistake in the bubble sort alg
    the Correct code is
    The code is in Kotlin :
    private fun bubbleSort(list: Array) {
    var temp: Int
    for (i in 0 until list.size - 1) {
    for (j in 0 until list.size - i - 1) {
    if (list[j] > list[j + 1]) {
    temp = list[j + 1]
    list[j + 1] = list[j]
    list[j] = temp
    }
    }
    }
    println(list.joinToString())
    }
    The mistake is in the first loop, the last iteration is unnecessary so it need to be removed

    DSA is all about building logic, not just viewing videos. Please don't waste time on a 5-hour video. In my experience, it takes around 8 months to 1.2 years to master DSA in Java. However, it's important to note that DSA is not just about learning specific algorithms and data structures. It's also about learning how to approach problems and write code efficiently. Therefore, it's crucial to understand the fundamental concepts and principles behind DSA. While this guy may teach DSA, you also need to know how to approach problems and write efficient code

      why we shouldn't waste 5 hrs on this video when we have to waste 1.2 years!!! It's Does matter if we waste 5 hours it's Negligible in 1.2 years although Programming is dead in this AI Era. Why someone would Learn Programming in this Ai era when Ai is sufficient to do 40 people's work alone!!! Companies are shifting in Ai world to save money that's why all the layoff happens!!

    Is data structures and algorithm concepts the same for Java and Python? If I go through this video, do I have to go through data structures and algorithms in Python as well? A suggestion can help me.

    • @AbhinavRaj_P
      @AbhinavRaj_P ปีที่แล้ว +3

      Yes, the fundamental concepts of data structures and algorithms are almost same across all programming languages. The core ideas of algorithms such as sorting, searching, and various data structures like arrays, linked lists, trees, etc., are not at all any language specific.
      However, there are syntax differences, and built-in functions or libraries that you might use to implement certain algorithms or data structures are quite different for each language.
      So, I think you need to go through the with the implementation of those algorithms in python for handy experience.
