|
* Kruskal’s algorithm is the concept that is introduced in the graph theory of
|
||||||
|
* discrete mathematics. It is used to discover the shortest path between two
|
||||||
|
* points in a connected weighted graph. This algorithm converts a given graph
|
||||||
|
* into the forest, considering each node as a separate tree. These trees can
|
||||||
|
* only link to each other if the edge connecting them has a low value and
|
||||||
|
* doesn’t generate a cycle in MST structure.
