WebIf your graph has a relatively small number of nodes and is fairly dense (lets say at least 5% of all possible connections exist) then you may find it is more space efficient to create an adjacency matrix rather than using edge lists. This would require just one bit per possible (directed) connection, and n*n bits total where you have n nodes. WebAlso, you will find working examples of adjacency list in C, C++, Java and Python. An adjacency list represents a graph as an array of linked lists. The index of the array represents a vertex and each element in its linked …
