Identifying last loop when using for each

Question

I want to do something different with the last loop iteration when performing \'foreach\' on an object. I\'m using Ruby but the same goes for C#, Java etc.

Answer 1

Is this elegant enough? It assumes a non-empty list.

  list[0,list.length-1].each{|i|
    puts "Looping:"+i # if not last loop iteration
  }
  puts "Last one:" + list[list.length-1]
