Topic content:

The factor of a positive integer is all positive integers that can be divisible by it. And if a number is exactly equal to the sum of factors other than itself, this number is called the end number. For example 6=1+2+3 (6 of the factor is the one-to-be).

Now you are going to write a program that reads two positive integers n and M (1<=n<m<1000) and outputs all the n,m in the range.

Tip: You can write a function to determine whether a number is complete.

Input format:

Two positive integers, separated by a space.

Output format:

In the meantime, all the numbers are separated by a space, and the last number has no space behind it. If not, output one line of text:

NIL

(output nil three uppercase letters plus a carriage return).

Input Sample:

1 10

Sample output:

6
