Keyword Occurrence Counter

You are given a review text along with a keyword. Your task is to count the number of times the exact keyword appears in the review.

Note:

• The review is a string that may include punctuation.
• The keyword should match exactly one of the tokens obtained by splitting the review on whitespace.
• Case sensitivity matters.

For example, if the review is "The product is great. The product is worth the money." and the keyword is "product", then the output should be 2.
