repeat (repeat)
ask [Input an item to be shuffled:] and wait
add (answer) to [shuffle between v]
end
repeat (length of [shuffle between v])
set [# of item that is being shuffled v] to (pick random (1) to (length of [shuffle between v])
repeat until <not <[items that already had their positions shuffled v] contains (item (# of item that is being shuffled) of [shuffle between v])>>
set [# of item that is being shuffled v] to (pick random (1) to (length of [shuffle between v])
end
set [item that had its position shuffled v] to (item (# of item that is being shuffled) of [shuffle between v])
delete (item # of (item that had its position shuffled) in [shuffle between v]) of [shuffle between v]
insert (item that had its position shuffled) at (pick random (1) to ((length of [shuffle between v]) + (1))) of [shuffle between v]
add (item that had its position shuffled) to [items that already had their positions shuffled v]
end
set [shuffle is v] to (item (1) of [shuffle between v])
