Finding Rotten Apples Explained

The state of apples is given in a list, where rotten apples are represented as '0', and fresh apples as '1'.

The function takes this list as input and returns the positions (indices) of rotten apples in a list format.

Copy
def solution(apples):
    return [index for index, apple in enumerate(apples) if apple == 0]

• Using enumerate(apples), retrieve the index and value of each apple.

• Filter out rotten apples with if apple == 0.

• Use list comprehension to return all indices of rotten apples.

Copy
print(solution([1, 0, 1, 0, 1]))  # Output: [1, 3]
