Worked Example

cpp
int lo = 0, hi = n - 1;
while (lo <= hi) {
  int mid = lo + (hi - lo) / 2;
  if (a[mid] == x) return mid;
  if (a[mid] < x) lo = mid + 1; else hi = mid - 1;
}

  • Lokendra Kaul

    Got this exact concept in my last interview round. This post would have saved me.

  • Amit Kanitkar

    Crisp and exam-focused. No fluff. More like this.

    • Devdutt Walia

      The 2023 PYQ uses the same idea, just dressed up with extra constraints.

    • Mansi Desai

      Yes, weightage held steady the past three cycles.

  • Tanmay Malhotra

    Could you add one more example on the boundary case? I keep tripping on it in mocks.

  • Rashmi Mishra

    The diagram up top is doing a lot of heavy lifting. More of these please.

    The cheat-sheet table at the end deserves a poster version honestly.

  • Sara Dhawan

    Sir, is this enough depth for GATE or should I also do the standard textbook chapter?

  • Yashika Yadav

    The step-by-step method works. Tried it on yesterday's sectional and saved ~4 minutes.

  • Palak Kar

    Typo in the code block? Looks like the loop bound should be inclusive.
