2685. Count the Number of Complete Components

Leetcode Solutions

DFS Traversal and Edge Count Verification

  1. Initialize a list G to represent the graph, where G[i] contains the neighbors of vertex i.
  2. Initialize a visited array visited to keep track of visited vertices.
  3. Initialize a counter ccc to count the number of complete connected components.
  4. Iterate over each vertex i from 0 to n-1: a. If i is not visited, perform DFS starting from i. b. In DFS, increment the vertex count v and the edge count ce (since each edge is counted twice). c. After the DFS, check if ce is equal to v * (v - 1) (since each edge is counted twice). d. If the condition is true, increment ccc.
  5. Return the value of ccc.
