Input format: Each input contains 1 test case. Each test case first gives a positive integer N not exceeding 1000, and then gives N positive integers not exceeding 1000 to be classified. Numbers are separated by spaces. Output format: For the given N positive integers, calculate A1~A5 according to the title and output them sequentially in one line. Numbers are separated by spaces, but there must be no extra spaces at the end of the line. If one of the numbers does not exist, then output…
