$10pts$

Given a dictionary $d,$ that contains employee information in the format $\{$employee$\_$id: $\{\text{'}$name$\text{'}$: name, 'position': position, 'department': department$\}\},$ returns a new dictionary with the employee information by department using the format department: $[\{\text{'}$emp$\_$id$\text{'}$: employee$\_$id$,$ 'name': name, 'position' : position $\},\{\text{'}$emp$\_$id$\text{'}$: employee$\_$id$,$ 'name': name, 'position': position$\}]\}.$ Note that employee id becomes the key and it disappears as a value in the inner dictionary. Do not mutate $($change$)$ the original dictionary.
