Do you know how to explain this solution? Please do not write the program but explain step by step process for obtaining solution thank you

(8 pts) Let the array form of the disjoint sets be as follows A I-4 l 1 I1 3 3 5 5 I-3 l 8 l 8 l 10 I10 l 12 l 12 l il 1 2 l 3 l 4 l l 6 l 7 l 8 l 9 I10 l11 I12 I13 I14 l Assume that we are using union by rank and find with path compression. Show the array form of the resulting disjoint sets after the operation union(6, 13) Solution: After the operation union(6, 13), the array form is as follows A I-4 l 1 I1 3 1 1 5 l 1 l 8 l 8 l 10 I 8 l 8 l 12 l il 1 2 l 3 l 4 l l 6 l 7 l 8 l 9 I10 l11 I12 I13 I14 l
