Given a weighted graph, find the maximum cost path from given source to destination that is greater than a given integer x. The path should not contain any cycles. For example, consider below graph, Let source=0, k=40. The maximum cost route from source vertex 0 is 0-6-7-1-2-5-3-4 having cost 51 which is more than k.

Johnson’s Algorithm finds a shortest path between each pair of nodes in a weighted graph even if negative weights are present.

For a directed graph, a node may be inserted, but there need not be an arc to or from it; or an edge can be inserted between two existing nodes. Some definitions that are associated with graphs: Two vertices are said to be adjacent if there is an edge connecting them. A path in a graph is a sequence of vertices and edges.
