The Competitive Programming Series #2 is an engaging event hosted by the Google Developer Group CUB, aimed at enhancing problem-solving skills through algorithmic challenges. This series will focus on preparing students for competitive programming contests by introducing them to common problem types, coding strategies, and optimization techniques. The goal of this event is to foster collaboration, improve participants' programming abilities, and provide a hands-on learning experience in a fun, competitive environment. The event will be open to all skill levels, from beginners to advanced coders, and we aim to build a strong community of enthusiastic programmers at Constructor University.
