+
+1. **Initialization:** Start by setting the distance of the source vertex to itself as 0,
+and the distance of all other vertices to infinity.
+
+2. **Relaxation:** Iterate through all edges in the graph |V| - 1 times, where |V| is

+for all vertices. This is done by relaxing each edge: if the distance to the destination

+
+3. **Detection of Negative Cycles:** After the |V| - 1 iterations, perform an additional iteration. 
+If during this iteration, any of the distances are further reduced, it indicates the presence of a

+## Shortest Path
+### Bellman-Ford
+Dijkstra's algorithm is a graph algorithm used to find the shortest path from a single source vertex to all
+other vertices in a weighted graph with non-negative edge weights. It was developed by Dutch computer scientist 
+Edsger W. Dijkstra in 1956.
+
+Here's a step-by-step explanation of how Dijkstra's algorithm works:
+
+1. **Initialization:** Start by selecting a source vertex. Set the distance of the source vertex to itself as 0, and the 
+distances of all other vertices to infinity. Maintain a priority queue (or a min-heap) to keep track of vertices
+based on their tentative distances from the source vertex.
+
+2. **Selection of Vertex:** At each step, select the vertex with the smallest tentative distance from the priority queue. 
+Initially, this will be the source vertex.
+
+3. **Relaxation:** For the selected vertex, iterate through all its neighboring vertices. For each neighboring vertex,
+update its tentative distance if going through the current vertex results in a shorter path than the current 
+known distance. If the tentative distance is updated, update the priority queue accordingly.
+
+4. **Repeating Steps:** Repeat steps 2 and 3 until all vertices have been visited or until the priority queue is empty.
+
+5. **Output:** After the algorithm terminates, the distances from the source vertex to all other vertices will be finalized.
+
+Dijkstra's algorithm guarantees the shortest path from the source vertex to all other vertices in the graph,
+as long as the graph does not contain negative weight edges. It works efficiently for sparse graphs with
+non-negative edge weights.
+
+The time complexity of Dijkstra's algorithm is O((V + E) log V), where V is the number of vertices and E is 
+the number of edges in the graph. This complexity arises from the use of a priority queue to maintain the tentative 
+distances efficiently. If a simple array-based implementation is used to select the minimum distance vertex in each
+step, the time complexity becomes O(V^2), which is more suitable for dense graphs.
+
+#### Implementation with Slices
+Steps:
+1. Initialize distances with maximum float/integer values except for the source vertex distance, which is set to 0.
+2. Iterate numVertices - 1 times (where numVertices is the number of vertices in the graph).
+3. Select the vertex with the minimum distance among the unvisited vertices.
+4. Relax the distances of its neighboring vertices if a shorter path is found.
+5. Mark the selected vertex as visited.
+
+**Time Complexity:** O(V^2), where V is the number of vertices in the graph. This is because finding the 
+minimum distance vertex in each iteration takes O(V) time, and we perform this process V times.
+**Space Complexity:** O(V^2) for storing the graph and distances.
+
+#### Implementation with Heap
+Steps:
+* Similar to the slice implementation but instead of linearly searching for the vertex with the minimum distance, 
+we use a heap to maintain the priority queue.
+* The priority queue ensures that the vertex with the smallest tentative distance is efficiently selected
+in each iteration.
+
+**Time Complexity:** O((V + E) log V), where V is the number of vertices and E is the number of edges in
+the graph. This is because each vertex is pushed and popped from the priority queue once, and each 
+edge is relaxed once.
+**Space Complexity:** O(V) for storing the priority queue and distances.

+## Shortest Path
+### Floyd-Warshall
+The Floyd-Warshall algorithm is a dynamic programming algorithm used to find the shortest paths between 
+all pairs of vertices in a weighted graph, even in the presence of negative weight edges (as long as there
+are no negative weight cycles). It was proposed by Robert Floyd and Stephen Warshall.
+
+Here's a step-by-step explanation of how the Floyd-Warshall algorithm works:
+
+1. **Initialization:** Create a distance matrix `D[][]` where `D[i][j]` represents the shortest distance between
+vertex i and vertex j. Initialize this matrix with the weights of the edges between vertices if there 
+is an edge, otherwise set the value to infinity. Also, set the diagonal elements `D[i][i]` to 0.
+
+2. **Shortest Path Calculation:** Iterate through all vertices as intermediate vertices. For each pair of 
+ vertices (i, j), check if going through the current intermediate vertex k leads to a shorter path than
+ the current known distance from i to j. If so, update the distance matrix `D[i][j]` to the new shorter
+ distance `D[i][k] + D[k][j]`.
+
+3. **Detection of Negative Cycles:** After the iterations, if any diagonal element `D[i][i]` of the distance 
+ matrix is negative, it indicates the presence of a negative weight cycle in the graph.
+
+4. **Output:** The resulting distance matrix `D[][]` will contain the shortest path distances between all 
+ pairs of vertices. If there is a negative weight cycle, it might not produce the correct shortest paths, 
+ but it can still detect the presence of such cycles.
+
+The time complexity of the Floyd-Warshall algorithm is O(V^3), where V is the number of vertices in the graph.
+Despite its cubic time complexity, it is often preferred over other algorithms like Bellman-Ford for dense
+graphs or when the graph has negative weight edges and no negative weight cycles, as it calculates shortest
+paths between all pairs of vertices in one go.
