What you need to know to make an informed choice.
Abbott and Costello’s signature wordplay sketch “Who’s on First?” is one of the most renowned comedic routines of all time. Trying to describe the routine here will do it little justice, you’ll just have to watch it yourself. As funny as it may be, the sketch reveals a crucial fact: names are important. Good names should be self-explanatory, precise and reveal intent. Bad names leave people confused and aggravated and should be avoided at all cost. When we write code, we must always think about variable names, function names, file names, etc. But naming things is hard. Phil Karlton probably said it best: “There are only two hard things in Computer Science: cache invalidation and naming things.”
These graphs are isomorphic, even though they look much different. For starters, they both have the same number of nodes with each node containing the same number of edges. They are isomorphic because each node in the first graph maps to a corresponding node in the second graph while maintaining certain properties. For example, the node A can be mapped to node 1 while maintaining its adjacency in the second graph. In fact, all nodes in the graph have an exact one-to-one correspondence while maintaining adjacency.
