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;
}

Comments

  • Suresh Reddy

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

  • Sneha Tuli

    The mistakes section is painfully accurate. Made all three last mock.

  • Jaideep Tiwari

    Adding this to my error log workflow — the categories line up perfectly.

  • Nivaan Sahni

    This finally made Computer Networks PYQ Analysis 2023 click for me. The worked example is exactly the level of detail I needed.

  • Aaditya Gupta

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

    • Tejas Patil

      +1, asked the mentor in today's session and got the same explanation.

  • Devraj Khurana

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

    • Krishna Birla

      Same here — re-reading the invariant section twice fixed it for me.

  • Lokendra Krishnan

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

    • Kavya Bhat

      Same here — re-reading the invariant section twice fixed it for me.

  • Yogita Sethi

    I solved the practice set after reading this and scored 8/10 — the two I missed are both covered in the pitfalls list.

    • Ajay Upadhyay

      Check the linked practice set; question 4 is the boundary case you mean.

    • Raghav Panda

      We covered this in the weekend live class too — recording is up.

  • Pari Dash

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

  • Jaideep Tiwari

    Adding this to my error log workflow — the categories line up perfectly.

    • Prashant Bhandari

      Textbook chapter is optional after this unless you want proofs.

    • Yamini Dhawan

      It reads fine on mobile for me after the last refresh.
