Starter Code

from typing import List


def reveal_letters(word: str, visible_letters: List[str]) -> str:
    """Reveal the given letters in a hidden word.
    
    Args:
        word: The word whose letters need to be revealed.
        visible_letters: A list of letters that should be visible in the word.
    
    Returns:
        The word with visible letters shown and all others blanked-out.
    
    Example:
        If the word is "hello" and visible_letters is the list ['e', 'o'],
        The resulting string would be "_ e _ _ o". Separate each character
        with a space to make it easier to read.
    """
    pass
