you must include a while loop in this function

you should not us any of the following:

  • dictionaries or dictionary methods
  • try-except
  • break and continue statements
  • recursion
  • map / filter

def longest_chain(lst: List[int]) -> int: II II II Given a list of integers, return the length of the longest chain of 1's that start from the beginning. You MUST use a while loop for this, and are not allowed to use a for loop. Hint: A good way to start is to define a stopping condition, and have a variable that keeps track of how many 1's you've seen thus far, if any. Precondition: <lst> will only contain the integers 1 and 0. >>> longest_chain([1, 1, 0]) 2 >>> Longest_chain([0, 1, 1]) >>> longest_chain([1, 0, 1, 1]) 1 pass
