Week 2: Wednesday
-----------------

Q1. (50)

Input a positive integer and check if it is perfect.  A
number is perfect if it is equal to the sum of its proper
divisors (including 1 but excluding itself).

Example: 6 is a perfect number since 1 + 2 + 3 = 6.

Q2. (50)

Input a positive integer (assume numbers less than 10000).
Reverse the number and check if it is a palindrome.  A
palindrome is a number that can be read the same way in
either direction and is still the same.

Example: If 1782 is the input, the reverse is 2871, and it
is not a palindrome.
If 1780 is the input, the reverse is 871, and it is not a
palindrome.
If 1771 is the input, the reverse is 1771, and it is a
palindrome.
