HihoCoder is a brand founded in 2012 that aims to bridge the communication gap between programmers and businesses while providing a platform for programming enthusiasts to enhance their coding skills. Since its inception, HihoCoder has made significant improvements and enhancements to its platform based on valuable feedback from participants in the Microsoft Programming Beauty Challenge. The brand offers two main services: the HihoCoder Monthly Contest (referred to as the Monthly Contest) and the Hiho Algorithm Training Class (referred to as Hiho Class).

The Monthly Contest is an online programming points competition based on the Elo Rating System. The contest features problem sets created by ACM team members from top-class universities like Peking University, and the evaluation environment is crafted by experienced technical professionals from renowned online judge platforms. Participating in the Monthly Contest allows you to accurately gauge your programming skills and identify areas for improvement while also showcasing your abilities to potential employers.

The Hiho Algorithm Training Class is a series of training competitions designed for programming enthusiasts to learn and strengthen their knowledge of algorithms and programming in a structured manner. The powerful technical team behind HihoCoder has developed an effective training methodology based on the wisdom gained from algorithmic theory, algorithmic arts, and information technology competitions. This training program provides beginners with an excellent pathway to enter the world of programming.

HihoCoder's technical team consists of members from the original Beijing University POJ (PKU Online Judge) development team. With a decade of experience, POJ has accumulated a vast collection of contest problems from various regions and universities worldwide. The platform offers 24/7 online submission and evaluation services and has received nearly 10 million program submissions as of July 2013.

Additionally, POJ has organized award-winning monthly contests with original problem sets and has supported renowned companies such as Microsoft, Baidu, Tencent, NetEase Youdao, and more in hosting programming competitions.
