Recaman's Sequence — DSA Technical Interview Questions & Answers

Recaman's Sequence

Recaman's Sequence

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

Technical Interview Tip: What is Recaman's Sequence? Show this: the smallest Recaman's Sequence example you can type. Trap: only saying “Recaman's Sequence” with no example.

Code Examples for Recaman's Sequence

Recaman's Sequence — working example

# Recaman's Sequence
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)

Recaman's Sequence: dry-run [4, 1, 3]. Say the list after one step.
