If we add 16 as a node to the graph below, which node(s) will it connect to?
the knowledge tag is indicating knowledge of computer science concepts, not external 'data' related to the graph.
This puzzle is derived from, but very much different from, another puzzle.
Nodes 8, 11, and 12 are not included because they are completely disconnected from each other and the other nodes from 0 through 15. They're still disconnected from the rest of the graph when we include 16.
The relation has something to do with comparing strings.
An edit distance (metric) is involved.
