Binary Vectorizer

Given a vocabulary list and a text, create a binary vector where each position is 1 if the corresponding vocabulary word appears in the text, and 0 otherwise.

Input format:

Line 1: Comma-separated vocabulary words (already sorted)
Line 2: The text to vectorize

All comparisons are case-insensitive.

Output: A list of 0s and 1s.

Example:

Input:

cat,dog,fish,the
the cat sat

Output:

[1, 0, 0, 1]

Reasoning:

Step 1: Parse vocabulary ["cat", "dog", "fish", "the"]

Step 2: Check each vocab word in text "the cat sat" (lowered) contains: cat=yes, dog=no, fish=no, the=yes

Step 3: Build vector [1, 0, 0, 1]

Constraints:

Vocabulary is provided comma-separated
Case-insensitive matching
Output: Python list of 0s and 1s
