Merge two sorted arrays with O(1) extra space

Merge two sorted arrays with O(1) extra space

  • Merge two sorted arrays with O(1) extra space is a DSA topic. In plain words you use it for names A→Z in the roll list. Don’t start with a slogan — start with that picture.
  • Smallest example: n log n vs n². Type it, run it, and say what you see. If you can do that from memory, you know Merge two sorted arrays with O(1) extra space.
  • From the example next to this theory: Merge two sorted arrays with O(1) extra space: dry-run [4, 1, 3].
  • Trap: unstable sort when equal keys matter. Fix that before you talk about advanced DSA.
  • Viva: what is Merge two sorted arrays with O(1) extra space? Then show n log n vs n². Then name the trap.

Technical Interview Tip: What is Merge two sorted arrays with O(1) extra space? Show this: n log n vs n². Trap: unstable sort when equal keys matter.
