Complexities of Graph Operations
Explore the time complexities of basic graph operations using adjacency lists and adjacency matrices. Understand how vertex and edge manipulations differ in efficiency and when to use each representation, helping you write better Python code and prepare for coding interviews.

Time Complexities
Below, you can find the time complexities for the 4 basic graph functions.
Note that, in this table, V means the total number of vertices and E means the total number of edges in the Graph.
| Operation | Adjacency List | Adjacency Matrix |
|---|---|---|
| Add Vertex | O(1) | O(V2) |
| Remove Vertex | O(V+E) | O(V |
