### Problem 346 in project euler

This problem was easy to me that make my brain to take a rest.

the steps to solve

1. I had to find range of base that number can cover 10^2

It was sqrt of 10^2 include itself.

2. generater all possible base numbers

ex) in 2 base

11, 111, 1111 ...

3 7 15

3. exclude 2 digit number.

4. put set to real number

5. sum of set

this is my solution.
