Write a Python function `find_min_length` that takes a list of lists as input and returns the length of the smallest list within it. If the input list is empty, return `0`. #### Example Usage ```python [main.nopy] print(find_min_length([[1], [1, 2]])) # Output: 1 print(find_min_length([[1, 2], [1, 2, 3], [1, 2, 3, 4]])) # Output: 2 print(find_min_length([[3, 3, 3], [4, 4, 4, 4]])) # Output: 3 print(find_min_length([])) # Output: 0 ```
def find_min_length(lst):
"""
Find the length of the smallest list in a list of lists.
Args:
lst (list of lists): A list containing sublists.
Returns:
int: The length of the smallest sublist, or 0 if the input list is empty.
"""
# Check if the input list is empty
if not lst:
return 0
