How to Solve a Google Graph Based Coding Challenge
In this video, Liz breakdowns how to solve a graph problem she encountered in a real Google interview.
Challenge prompt:
You are tasked with splitting the 7th-grade class into two teams for a soccer game. Given a list of students and their “enemies” aka “the kids they can’t be on the same team as”, determine whether it is possible to split the class in two in such a way that no child is on the same team as any of their enemies. If possible, return the two teams.
