Hi,

I need help in sorting of array. My array is like this. 

@array = (
    {
        level => 1,
        department = 'Office of President',
    },
    {
        level => 2,
        department = 'Recruiting',
    },
    {
        level => 2,
        department = 'Software',
    },
    {
        level => 3,
        department = 'MIS',
    },
    {
        level => 3,
        department = 'System Operations',
    },
    {
        level => 2,
        department = 'Pipe line',
    },
);

basically this is made for tree like structure, when i print this array , it prints like this : 
Office of the President
   Recruiting
   Software
     MIS
     System Operations
   PipeLine

Currently the department is not sorted alphabetically beacuse my array is created on the basis of level and it is in sequence. Now i want to sort the department alphabetically. How will i do this. I want this array print like this : 
Office of the President (Make this as base level)
  PipeLine
  Recruiting
  Software
      MIS
      System Operations
etc.....
