    I knew this but I have my DSA theory test and the teacher demands a perfect step-wise answer. This is pure gold ❤

    Wow indeed, the best video to explain binary search's time complexity. I was looking at my friend's notes and this was already written before so I didn't understand what was going on but this explanation made it very clear. It's short and good-paced to understand. Thank you!

    Thank you! I learned this like 5 years ago and need to know it again and couldn’t for the life of me remember how to mathematically represent the runtime of binary search so you really helped me out!!!!!

    So well described, I modified and used it for the ternary search my professor used as a homework problem.

  • @patryk5823
    @patryk5823 4 роки тому

    Hello, I have a question. I wrote a program where I used two times binary search into two functions. So I have to find time complexity appart from these two and plus them? Like O1() + O2() or O(...+....)?

  • @aryasarkar3514
    @aryasarkar3514 3 роки тому

    Mam what is the meaning of time taken for the checks?

  • @jobearnest
    @jobearnest 4 роки тому

    I have a small doubt in this algo. For method call binary_search([3,5], 2, 0, 1) what would be the result? I guess you need to handle -1 situation or am I missing something here?

    • @elan2199
      @elan2199 4 роки тому

      The result will be -1, since we have:
      if(start == end)
      return -1;
