Find the edges from the graph. 1-2 2-3 3-4 3-6 4-5 1-5 As there are six vertices, we'll create six disjoint-sets. Consider the edge 1-2, FIND (1)=1 FIND (2)=2 UNION (1,2) S1,S2 will be merged to S1 and set-representative of S1 will now be 1. Consider the edge 2-3, FIND (2)=1 diagram of the i. illecebrosus https://bowlerarcsteelworx.com
