AtCoder Beginner Contest 308

Sponsors

e-Seikatsu Co.,Ltd.

Hi everybody! My name is Akira Matsuzaki, CTO of e-Seikatsu. (It means “Good Life” in Japanese.) We are a vertical B2B SaaS provider to innovate the Japanese real estate market, with the mission of “Create society where comfortable life circulates”.

We’ve given sponsorships of the ICPC Asia Regionals, JOI (Japan Olympiad in Informatics), SuperCon (a Japanese HPC competition for high-school students), and other computing competitions and events every year in the past. Through these activities, we support competitive programming and its participants, as well as the students who aim for it.

I believe that the experience of competitive programming is important and meaningful for the general software development. Because it’s a very useful place to acquire important skills to develop high-quality and high-performance software: consider approaches to solving problems, select best algorithm, assume and understand the intentions of the questioners, and of course, the coding skills needed to implement your thinking. In fact, there are many engineers in our team who did competitive programming when they were students or who still love and do it.

On the other hand, I feel strongly that there are insufficient female programmers and engineers in Japan; this is very unfortunate. Therefore, we’ve given sponsorships the Women’s Division of the JOI to advance STEM education for women in Japan. So, when I heard about CodeQUEEN in this context, I decided immediately to sponsor this new initiative.

I firmly believe that gender should not be a determining factor for individuals aspiring to become programmers and engineers. We hope that you’ll become interested in the field of competitive programming or software programmers and engineers, then will have an opportunity to growth your potential in there through this competition.

freee K.K.

freee has “Empower Small Businesses to Take Center Stage.” as its mission and aims to build an integrated management platform that allows everyone the freedom to run their own business. freee keep customer’s accounting, human resources, and other business data as a cloud-based ERP and provide functions to improve customer’s work efficiency.

Records of daily transactions and time and attendance gradually become large volumes of data as the company grows, it is necessary to be conscious of computational efficiency in order to present information by aggregating these in real time. For example, freee currently has over a billion records, this number exceeds the 10⁹ often seen in AtCoder questions. Of course, processing all the elements one by one would be time consuming.

Calculation of taxes and salaries requires the ability to convert the complex specifications of laws that change year by year into logic and accurately put them into code. In addition, since the system is loosely coupled by dividing it into microservices so that the complexity of each domain area does not affect the others, data must be efficiently federated while maintaining consistency among the services.

For these issues, we believe that “Ability to select appropriate data structures and algorithms for the problem” and “Ability to implement quickly while considering edge cases” that AtCoder users have will be very useful.

Also, freee believes that in order to realize a society in which anyone can run their business freely, it is important for freee’s employees themselves to have diverse attributes and backgrounds, and for each individual to work naturally.

freee, which is based on the premise that “Everyone has some kind of minority element.”, is working to support and create an environment where diverse people, such as gender, LGBTQ+, people with disabilities, and globals, can be active.

We participated as a sponsor this time because we want AtCoder users to know about freee, and we also want to work together with them to develop a society in which diverse people can perform better. We hope that this competition will help you to become more interested in engineering and to think about your future career.

Microsoft Development Co., Ltd.

Microsoft is proud to be sponsoring this exciting coding contest for female software engineers and students. The competition is open to all technical minded professionals and students from across Japan and is an opportunity to show off your code writing skills.

At Microsoft, we believe that coding, data science, and AI are invaluable skills for the 21st century and beyond, we also believe that empowering women to pursue careers in technology means a brighter future for all. We are passionate about creating an environment where women feel emboldened to pursue their strengths and succeed.

Through this contest, we hope to further engage with and empower the next generation of female computer engineers, software developers, and problem- solvers. We are delighted to offer our support to help foster and advance the amazing work of young female coders and excited to be part of the journey. Sign up for this coding contest and make your mark now. We look forward to seeing the submissions and are excited to find out who will be chosen as the winner! Good luck to all the participants!
