In the case of 1,2,3,4,5,6 itemOffset will work, but a warning about itemOffset:
itemOffset("2","23,24,2") returns 1 because the string "2" matches the first 2
of 23. This is not applicable to this exercise, but might save somebody some
trouble. In a previous project I assumed that it looked for a matching *item*,
but in fact it looks to match a *string*. Arrgh. The docs are correct, by the
way.
