100-999 print out all the "number of Narcissus", the so-called "Narcissus number" refers to a three-digit number, which is equal to the digits of the cube and the number itself. For example: 153 is a "Narcissus number", because cubic cubic cubic +3 +5 1 = 153.
If a number is exactly equal to the sum of its factors, called the number "perfect number", also known as the number of complete or perfect number. For example: The first is a perfect number 6, it is about the number 1,2,3,6, 6 is removed outside itself, adding the number of the remaining 3, 1 + 2 + 3 = 6. The second number is the 28 completely, it is about several 1,2,4,7,14,28, 28 itself is removed, the remaining number of the sum 5, 1 + 2 + 4 + 7 + 14 = 28. So the question is, find the perfect numbers less than 1000 what?
