Solution: Check If a Path Exists between Two Vertices

The problem involves determining if a valid path exists between a source and a destination vertex in a bidirectional graph represented by a 2D list of edges. A breadth-first search (BFS) approach is utilized, where the graph is represented as an adjacency list. The algorithm explores vertices using a queue and tracks visited nodes. If the destination is reached during exploration, it returns TRUE; otherwise, it returns FALSE after all paths are checked. The time and space complexity of the solution is O(v + e), where v is the number of vertices and e is the number of edges.
