Equivalently, it stores a partition of a set into disjoint subsets. It provides operations for adding new sets, merging sets (replacing them by their union), and finding a representative member of a set. The last op… chipmunk gradle

"WebTo perform a union operation, we need to first perform two finds. After that, only O(1) time is required to perform the union operation. Therefore, we can replace each union(x, y) with three operations: A call to find(x). A call to find(y). A linking step between the nodes found this way. Going forward, we will assume that each union " - Sets union runtime
