You can always replace a foreach with a map by putting the complete loop body (including print and other maps) into the map and the list after.

But your test for uniqueness is overly complicated and buggy in edge cases.

Better just take simply the keys if %h and sort them.

But if I were you I'd hardcode the weekdays into an array anyway.
