Arrays and Hashes

Sort

• The sort function takes an array and sorts the elements stored into alphanumeric order.
• Example:
  

  @First = qw(beta alpha gamma); 
  @Result = sort(@First); 
  print "@Result\n"; 
  ==> alpha beta gamma 
  

• Note that the array is not sorted in place, rather a sorted copy is made. If you wish to sort an array in place, you must assign it back into the same variable.
• Example:
  

  @First = qw(gamma beta alpha); 
  @First = sort(@First); 
  print "@First\n"; 
  ==> alpha beta gamma
