Code sprint in a Google Developer Student Club (DSC) is an event where club members work together on a software project or feature for a concentrated period, which could last for a day, a few days or weeks. The goal is to learn new technologies, build software applications, and gain experience in contributing to open-source projects. The participants would be divided into teams based on their skills and interests. Club members would collaborate to solve problems, receive mentorship and training opportunities, network with peers, and showcase completed projects. The code sprint would provide valuable learning experiences for club members, preparing them for future careers in technology.
