The title is as follows: The existing array length is n+1, which contains 1 to n-2, the order is uncertain, of which two numbers appeared two times, now to find out the two digits. Example A={2, 3, 1, 4, 5, 2, 4}, this array length is 7, storing 1 to 5, but 2 and 4 appear two times, program output 2 and 4. Method 1 Brute Force search Main idea: For the number of I in the array, look for all the integers i+1 to the end, a number if it occurs two time
