#create a loop that loops until the current line variable is equal to 0

  #3 variables for first name, last name, and birthday at their given indexes
  #[0:16], [16:32], [32:40]

  #conditional statements to check to see if a stripped first name and a stripped last name == F and L respectively
    #set birthday = B

  #create a result variable that concatenates first name, last name, and birthday
  #append the variable to our list

  #update first and last index variables

  #update the current line variable with the new indexes
