Graph union find

WebDec 22, 2024 · Union-Find Algorithm can be used to check whether an undirected graph contains cycle or not. Note that we have discussed an algorithm to detect cycle. This is another method based on Union-Find. This method assumes that the graph doesn\’t contain any self-loops. We can keep track of the subsets in a 1D array, let\’s call it parent[].
