+ * @file floyd_warshall.cpp
+ * @brief Implementation of the Floyd-Warshall algorithm in C++
+ * 
+ * The Floyd-Warshall algorithm is used to find the shortest paths between all pairs of vertices
+ * in a weighted graph. It is particularly useful for dense graphs where the number of edges is
+ * close to the number of vertices squared. The algorithm can handle graphs with positive or negative
+ * edge weights but will not correctly handle graphs with negative weight cycles.
+ * 
+ * The algorithm works by initializing a distance matrix with the direct distances between vertices.
+ * Then, it iteratively updates the matrix by considering each vertex as an intermediate point and
+ * checks if a shorter path exists through that vertex. The time complexity of the algorithm is O(V^3),
+ * where V is the number of vertices in the graph, and the space complexity is O(V^2).
+ * 
+ * Limitations:
+ * 1. High time complexity: O(V^3), which may be impractical for very large graphs.
+ * 2. High space complexity: O(V^2), requiring significant memory for large graphs.
+ * 3. Cannot handle negative weight cycles: If such cycles exist, the algorithm cannot provide correct shortest paths.
+ * 
+ * Usage:
+ * This implementation reads the number of vertices and the adjacency matrix of the graph from standard input.
+ * The resulting shortest path distances between all pairs of vertices are printed to the standard output.
+ * 
+ * Example input:
+ * 4
+ * 0 3 INF 5
+ * 2 0 INF 4
+ * INF 1 0 INF
+ * INF INF 2 0
+ * 
+ * Example output:
+ * 0 3 7 5
+ * 2 0 6 4
+ * 3 1 0 5
+ * 5 3 2 0
