Bring the last date according to the code you typed!

I have a spreadsheet where I bring the client code and a date of visit, I would like a formula where through the code I bring the last example date Cod. Date of Visit 1 01/04/2018 2 01/04/2018 3 01/04/2018 1 04/06/2018

return 1 04/06/2018 2 01/04/2018 3 01/04/2018
