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;
}

    Is there a printable PDF of this? The free notes section has one for DBMS.

    Reading time says 1 min but I spent an hour taking notes. Worth it.

  • Dhruv Pal

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

      Textbook chapter is optional after this unless you want proofs.

    • Rahul Kelkar

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

  • Nandini Kelkar

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

  • Rahul Sahni

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

  • Major Iqbal

    Can we get a follow-up post that goes deeper into the edge cases?
