In Java, please solve and don't copy from wrong answers. I need the JAVA CODE, not an answer like answering the question. An array A contains n−1 unique integers in the range [0,n−1], that is, there is one number from this range that is not in A. Design an O(n)-time algorithm for finding that number. You are only allowed to use O(1) additional space besides the array A itself. DO NOT SORT THE ARRAY. Must provide a test application with at least 2 sets of numbers. Hint: find smallest, largest, and sum. Compare the sum with the series summation??
