Trie Data Structure

Trie Data Structure is a DSA topic. In plain words you use it for a short Trie Data Structure example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Trie Data Structure example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Trie Data Structure.

From the example next to this theory — Trie Data Structure: dry-run [4, 1, 3].

Trap — only saying “Trie Data Structure” with no example. Fix that before you talk about advanced DSA.

Viva — what is Trie Data Structure? Then show the smallest Trie Data Structure example you can type. Then name the trap.

Exam tip

What is Trie Data Structure? Show this: the smallest Trie Data Structure example you can type. Trap: only saying “Trie Data Structure” with no example.

Example

# Trie Data Structure
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)

Trie Data Structure: dry-run [4, 1, 3]. Say the list after one step.
