Disjoint–Set Data Structure (Union–Find Algorithm)

WebA disjoint–set is a data structure that keeps track of a set of elements partitioned into several disjoint (non-overlapping) subsets. In other words, a disjoint set is a group of sets where no item can be in more than one set. It is also called a union–find data structure as it supports union and find operation on subsets.
