We want to use sed to locate all dates of the form ##/##/2023 and replace them with ##/##/23. That is, when we have a date whose year is 2023, we want to change it to the same date but without the "20". Why is the following sed command incorrect? Briefly explain how you would have to write a sed command to work correctly (do not provide the command, just explain how it would work).

sed 's/2023/23/g' somefile
