How to Check For Disjoint Sets in Python? To check for disjoint sets, we just have to check if there exists any common element in the given sets. If there are common elements among the two sets, the sets will not be disjoint sets. Otherwise, they will be considered disjoint sets. 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 paren...
For example, if there are two sets, A = {x, y} and B = {p, q}. As we can see that there are no common elements between the sets. We can take the intersection of two sets. A?B=?.A?B=?. Therefore, the intersection of two disjoint sets results in a null set. Two sets X...
Disjoint Set Data Structure - Learn about the Disjoint Set data structure, its operations, applications, and how it efficiently manages disjoint sets in algorithms.
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 ...
