Using a set of values from 0 to 8 as separate roots, perform the following unions using union-by-size. Show the result of each union. When sizes are the same, make the second tree be a child of the first tree. Notice the finds return roots, and a union will union two roots. union(find(0),find(2)) union(find(0),find(3)) union(find(0),find(4)) union(find(0),find(7)) union(find(1),find(5)) union(find(6),find(8)) union(find(5),find(8)) union(find(7),find(8)) Illustrate the array for the final forest(note that roots are not simply -1 when using union-by-size).
