Graph from adjacency list
WebDec 8, 2024 · 1. Let N be the node you are interested in findind the distance. Put every element that is accesible directly from N into a list/queue. Mark every element as not being reachable (false). For every element added in step 2, check their adjacency list and mark the nodes that are accesible as reachable (true). WebJun 17, 2024 · The 2 most commonly used representations of graphs are the adjacency list and adjacency matrix. The problems I’ll be solving are for sparse graphs (few edges), and the vertex operations in the adjacency list approach take constant (adding a vertex, O(1)) and linear time (deleting a vertex, O(V+E)).

WebNov 11, 2024 · The other way to represent a graph in memory is by building the adjacent list. If the graph consists of vertices, then the list contains elements. Each element is also a list and contains all the vertices, adjacent to the current vertex . By choosing an adjacency list as a way to store the graph in memory, this may save us space.
