a)LL Rotation — DSA Technical Interview Questions & Answers

a)LL Rotation

a)LL Rotation

  • a)LL Rotation is a DSA topic. In plain words you use it for a short aLL Rotation example in a short dry-run on paper. Don’t start with a slogan — start with that picture.
  • Smallest example: the smallest aLL Rotation example you can type. Type it, run it, and say what you see. If you can do that from memory, you know a)LL Rotation.
  • From the example next to this theory: a)LL Rotation: dry-run [4, 1, 3].
  • Trap: only saying “aLL Rotation” with no example. Fix that before you talk about advanced DSA.
  • Viva: what is a)LL Rotation? Then show the smallest aLL Rotation example you can type. Then name the trap.

Technical Interview Tip: What is a)LL Rotation? Show this: the smallest aLL Rotation example you can type. Trap: only saying “aLL Rotation” with no example.

Code Examples for a)LL Rotation

a)LL Rotation — working example

# a)LL Rotation
data = [4, 1, 3]
print("start", data)
if data[0] > data[1]:
    data[0], data[1] = data[1], data[0]
print("after one step", data)

a)LL Rotation: dry-run [4, 1, 3]. Say the list after one step.
