In this video, Liz explores a real-world application of using graphs to model how cybersecurity and malware attacks can be stopped. In the first part of this two-part video series, Liz introduces a real coding interview question that models a malware attack and walks through concepts such as disjoint sets, unions, and cycles to build the foundation for implementing a solution that will allow us to quarantine which nodes in a graph should be removed to reduce the impact of the attack.
