15. An integer is said to be a perfect integer if the sum of its factors, including 1, but not the number itsel,is equal to the number. For example, 6 is a perfect integer because 6-12 +3. Write a function (perfect) that determines whether a given number is a perfect integer Use this function in a program that determines and prints all perfect numbers between 1 and 1000. Print the factors of each perfect integer to confirm. Put your computer to hard work to find the fifth perfect integer. First is 6, second is 28, etc. (i) for 1000 (under Windows DOS or Cormand prompt) D:\temp\175-w0T\ha9-ans>time /t & hu9-q2.exe & time /t 09:45 AM Perfect integers between 1 and 1000: 6 123 28-2 4 7 14 496 = 1 + 2 + 4 + 8 + 16 + 31 + 62 + 124 + 248 09:45 AM under Linux: ?> date ; . /hw5_q5 ; date (ii) run to find the fifth perfect integer (ansver not given here for obvious reasons)
