What is DSA

DSA (what is) is a DSA topic. In plain words you use it for marks stored somehow in a viva board. Don’t start with a slogan — start with that picture.

Smallest example: array vs list vs hash — one line each. Type it, run it, and say what you see. If you can do that from memory, you know DSA (what is).

From the example next to this theory — What is DSA: dry-run [4, 1, 3].

Trap — reciting names with no cost. Fix that before you talk about advanced DSA.

Viva — what is DSA (what is)? Then show array vs list vs hash — one line each. Then name the trap.

Exam tip

What is DSA (what is)? Show this: array vs list vs hash — one line each. Trap: reciting names with no cost.

Example

# What is DSA
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)

What is DSA: dry-run [4, 1, 3]. Say the list after one step.
