##### Detecting cycles in a directed graph.

This technical problem involves finding cycles in a directed graph. One way to do this is to use a depth-first search algorithm, which can detect cycles by keeping track of which vertices have been visited. If a depth-first search algorithm reaches a vertex that has already been visited, then there is a cycle in the graph.

##### Shortest Path Between Two Words in a List

Given a list of words, this problem seeks to find the shortest path from one word to another such that each intermediate word is also in the list. For example, if the input list is [cat, rat, bat, mat], the shortest path from cat to mat would be cat -> bat -> mat.
