Arrays and Hashes

Reverse

• The reverse function takes an array and reverses the order of the elements stored.
• Example:
  

  @First = (1, 2, 3, 4); 
  @Result = reverse(@First); 
  print "@Result\n"; 
  ==> 4 3 2 1 
  

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

  @First = (1, 2, 3, 4); 
  @First = reverse(@First); 
  print "@First\n"; 
  ==> 4 3 2 1
