Build the functiоn line_tо_list. This functiоn should tаke in а string thаt will have some number of comma separated integers. It should turn that string into a list of integers if all of the following are true: When split, every item in the list can be converted into an integer. There are exactly four integers. If either of these conditions are violated, return None instead. Below are some examples along with the function's expected signature. Examples for line_to_list Input Output "1,2,3,4" [1, 2, 3, 4] "1,2,Z,4" None "1,2,3,4,5" None "1,2,3," None "1,2,3" None def line_to_list(line: str) -> list[int] | None:
