题目描述

The following -like pseudo code for function takes a list of positive integers and shuffles the integers in the list in a specific way, and returns the result as a list.

Three list methods are used below; For a list L, len(L) returns the number of items in L. L.append(x) adds the item x to the end of L. L.pop(idx) removes the item at the specified index idx from the list L and returns the removed item.

Given a list of positive integers, write a program to reconstruct a list such that .

function BlackBox( Banana ):
  if len( Banana ) <= 4 :
    exit("Too small Banana")
  Apple = [] # [] is an empty list
  Mango = 0
  Papaya = len( Banana )
  while( Papaya >= 2 ) :
    Kiwi = Banana[ Mango ]
    Apple.append( Kiwi )
    Banana.pop( Mango )
    Papaya = Papaya - 1
    Mango = ( Kiwi + Mango - 1 ) % Papaya
  # end of while
  Apple.append( Banana[ 0 ] )
  Pear = len( Apple ) - 1
  Orange = Apple[ Pear ]
  Lime = Apple[ 0 ]
  Coconut = Orange % Pear
  Melon = Apple[ Coconut ]
  Apple[ 0 ] = Melon
  Apple[ Coconut ] = Lime
  return ( Apple )
# end of function BlackBox
