Chapter 4, Problem 24(choose chapter or problem)
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. Write Java code that finds the integer that does not appear in such an array. Your solution should use a. O(n2) operations b. O(n) operations
