Hi guys, quick question about duplicate keys

Question about the task

Under discussion

I thought hashmaps couldn't have duplicate keys, but isn't that what is happening here when adding pairs with the same last name? Thanks!

Hi! "I thought hashmaps couldn't have duplicate keys" You think it well!!:) "when adding pairs with the same last name" - just try out!! Will not succeed:) Enter 10 pairs with 3 identical lastnames and print the result. HashMap will consist of 8 items. And the verifier will give pass!
