Check For Disjoint Sets Using The isdisjoint() Method Instead of the approach discussed above, we can use the isdisjoint() method to check for disjoint sets in python. The isdisjoint() method, when invoked on a

Further, taking union of sets A and B (E = A∪B) makes the resultant sets as, E = {1,4,5,2,3}, C = {6} and D = {7}. Let us drop the set names A, B, C, etc. In every set, one of the elements is called the representative element and the set name is taken to ...
In the below input graph, We have two components and thus two disjoint sets. Those are, Now, how we can find the disjoint sets. Here comes the find(X) & UNION (X,Y) ADT operation. The operation finds the set name and here we use array for that. We use a parent...

Disjoint Sets ADTThe basic operations on a disjoint set are the below ones:MAKESET(X): create a new set with element X UNION(X, Y): creating a set with X & Y and it deletes individual sets of X & Y. FIND(X): It finds the set in which X is there. (X can't be in two ...
