有没有哪位好心的达人碰巧做过的？能不能帮个忙贴一下？菜鸟想先骗个电面。跪谢了！
could you please provide at least one non-trivial coding problem that
required implementation of underlying distributed systems infrastructure,
custom data structures or optimized algorithms in C++. Your discussion
should be technically detailed and include idiomatic usage of core C++ to
adequately demonstrate the complexity of an insightful achievement.
