Consider an array of length n containing unique integers in random order and in the range 1 to n + 1. For example, an array of length 5 would contain 5 unique integers selected randomly from the integers 1 through 6. Thus, the array might contain 3 6 5 1 4. Of the integers 1 through 6, notice that the 2 was not chosen and is not in the array.
