An MMORPG game is under development. For the profile and inventory mechanics, it needs a query that calculates a list of game accounts whose inventory is overloaded with game items.

The result should have the following columns: username $|$ email $/$ items $/$ total$\_$weight.

$$ username $-$ account username

$$ email$-$account email address

$$iterms$-$total number of items in inventory

$$total$\_$weight $-$ total weight of items in inventory
