SnarkNews New Year Blitz Contest

My first contest in this year was SnarkNews New Year Blitz Contest (problems, results).

Due to the difference of time zones, it was somewhat a strange contest for me. I successfully celebrated 6:00 AM of New Year's Day.

Problem G was easy but nice. You are given a decimal number up to 250 digits. Consider all integers that can be obtained by permutating the digits, and compute the gcd of those integers.
