Modify the DepartmentNode.
The average number of employees in a tree node. Print it outwith two decimal places. Your code must compute it recursively.Hint: Create two recursive methods, one that returns the totalnumber of employees, and another that returns the number of nodes,then divide the two results. how do I make the avg read out to 2decimal places?
