A Week Later

Create a function which takes in a date as a string, and returns the date a week after.

Examples

week_after("12/03/2020") ➞ "19/03/2020"

week_after("21/12/1989") ➞ "28/12/1989"

week_after("01/01/2000") ➞ "08/01/2000"

Notes

• Note that dates will be given in day/month/year format.
• Single digit numbers should be zero padded.
