21.4 LAB: Parsing dates Write a program to read dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following that format is incorrect and should be ignored. The input ends with-1 on a line alone. Output each correct date as: 3/1/1990. Hint: Use string[startend] to get a substring when parsing the string and extracting the date. Use the split() method to break the input into tokens. Ex: If the input is: March 1, 1990 April 2 1995 7/15/20 December 13, 2003 -1 then the output is: 3/1/1990 12/13/2003

21.4 LAB: Parsing dates
Write a program to read dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following
that format is incorrect and should be ignored. The input ends with -1 on a line alone. Output each correct date as: 3/1/1990.
Hint: Use string[start:end] to get a substring when parsing the string and extracting the date. Use the split() method to break the input into
tokens.
Ex: If the input is:
March 1, 1990
April 2 1995
7/15/20
December 13, 2003
-1
then the output is:
3/1/1990
12/13/2003
