Disjoint Set Union (Union Find) HackerEarth

Web17 ago 2024 · 1) As explained above, Union-Find is used to determine the connected components in a graph. We can determine whether 2 nodes are in the same connected component or not in the graph. We can also determine that by adding an edge between 2 nodes whether it leads to cycle in the graph or not. Web8 giu 2024 · We will implement the DSU of the 2-edge-connected components without the Union by rank optimization, therefore we will get the complexity O ( log n) on average per query. To achieve the complexity O ( 1) on average per query, we need to combine the vertices of the cycle according to Union by rank, and then assign par [] accordingly. …

Web15 ago 2024 · It follows that r ( G) = 0 iff G is a forest, i.e. G has no cycles. Now consider what happens when you remove an edge from a graph G. If that edge is part of a cycle, you decrease E by 1 but do not change V or c, so r ( G) decreases by 1. If the edge is not part of a cycle, you additionally increase c by 1 (since you split a component ... Web5 feb 2024 · Another popular usage of DSU is in the Kruskal’s algorithm for finding the minimum spanning tree of an undirected graph. The straightforward implementation of Kruskal’s algorithm runs in time. DSU improves the asymptotic to be . In Kruskal’s algorithm, we first sort the edges by their weights in increasing order.

WebFind function of DSU will be used before including any edge in the MST to check if both the endpoints (nodes) of the edge belong to the same set or not. If they do not belong to the same set, we will include that edge in the MST as including the edge is not forming any cycle. Now we will use the union function of DSU to merge the two disjoint sets.
