Evaluation of a Postfix notation

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

Smallest example: the smallest Evaluation of a Postfix notation example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Evaluation of a Postfix notation.

From the example next to this theory: Evaluation of a Postfix notation — big-O describes how work grows with input size — ignore constants.

Trap — only saying “Evaluation of a Postfix notation” with no example. Fix that before you talk about advanced DSA.

Viva: what is Evaluation of a Postfix notation? Then show the smallest Evaluation of a Postfix notation example you can type. Then name the trap.

What is Evaluation of a Postfix notation? Show this: the smallest Evaluation of a Postfix notation example you can type. Trap: only saying “Evaluation of a Postfix notation” with no example.

Example

def demo(n):
    # O(1)
    x = n + 1
    # O(n)
    total = sum(range(n))
    # O(n^2)
    pairs = 0
    for i in range(n):
        for j in range(n):
            pairs += 1
    return x, total, pairs

print(demo(3))
