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.

Welcome to My Blog!

Happy New Year!

New Year's Day is a good day to start something. This year I decided to start writing a blog.

The main purpose of this blog is to keep track of my activities related to competitive programming (mainly for personal training). However, after contests, I may share my impressions or some problems, and those posts may be interesting to read.

There are three subpages in this blog:

List of Contests

Here I will list all contests I've participated. I don't think I can recollect everything, but I will do my best.

My Problems
Here I will list all problems I authored.

Upsolving

Here I put everything I'm planning to upsolve in the near future.

You can also go to these pages from links at the top-right corner.

Also, at the top-right corner, you can find the superset of contests I'm planning to participate (I may skip some of them). All times are in JST (GMT+9). You can also use it as a reminder :) 

Occasionally, I may post something unrelated to competitive programming, but I'm not sure now.
