Dynamic memory allocation — DSA Technical Interview Questions & Answers

Dynamic memory allocation

Dynamic memory allocation

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

Technical Interview Tip: What is Dynamic memory allocation? Show this: the smallest Dynamic memory allocation example you can type. Trap: only saying “Dynamic memory allocation” with no example.

Code Examples for Dynamic memory allocation

Dynamic memory allocation — working example

# Dynamic memory allocation
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)

Dynamic memory allocation: dry-run [4, 1, 3]. Say the list after one step.
