b)LR Rotation — DSA Technical Interview Questions & Answers

b)LR Rotation

b)LR Rotation

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

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

Code Examples for b)LR Rotation

b)LR Rotation — working example

# b)LR 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)

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