ab: In his article, the author shows how bipartite graphs can help in solving
two logic puzzles. One of them is “Cheryl’s Birthday problem", a
problem that was posted by Kenneth Kong, the host of a Singaporean TV
show, on his Facebook page and then went viral. Since then, the problem
has appeared in such esteemed publications as the New York Times, the
BBC and the Sydney Morning Herald.
