Given the following Disjoint Sets Array representation :

index	1	2	3	4	5	6	7	8	9	10	11	12
parent	1	2	9	12	11	10	1	2	9	12	9	2

Representing the elements 1 . . 12 after some Union-Find operations have already been performed on them:

a. Draw the tree structure for sets.

b. Redraw the tree structure after each of the following operations:

Find (6)

Find (5)

Union (6, 5)

c. Redraw the resulting array representation.
