What is an adjacency matrix - Javatpoint

WebAdjacency matrices are very good for dense graphs, and adjacency lists are good for sparse graphs. So it depends on what your graph looks like, but it also depends on whether you care more about running time or memory. If you represent your adjacency matrix as a hash table, you can get very good lookup times without using n^2 memory. WebWell, we combine them together and create a hybrid implementation! This is what an adjacency list is-- a hybrid between an adjacency matrix and an edge list. An adjacency list is an array of linked lists that serves the purpose of representing a graph. What makes it unique is that its shape also makes it easy to see which vertices are adjacent ... temperature in rising fawn ga
