Hi all,
I learnt some graph theory recently and I am quite fascinated by it. So, I wanted to check out some really interesting problems under that topic. What are some of the best problems that you've solved which have a graph algorithm (like shortest path, SCCs, euler tour, max-flow, bridges/articulation points) as their solution?
429A - Xor-tree & 499E - Array and Operations & 489B - BerSU Ball & 500B - New Year Permutation
Nice ones, but I was actually looking for problems like Hiking or Tanya and Password or Drazil and Tiles or Fox and Dinner i.e. where the reduction to a graph problem isn't very obvious.
