You are given cities numbers --- U and V, and your task is to find maximum happiness Marichka can get after travelling in some way(maybe through some intermediate cities) between cities U and V. If there is no way to get from the city U to the city V between them, then simply output -1. One of the most important skills a programmer needs to learn early on is the ability to pose a problem in an abstract way. HackerEarth uses the information that you provide to contact you about relevant content, products, and services. Note that, if at some point the length becomes $$0$$, the process is stopped.
