Inspired from this Wikipedia article.

Choose some sets such that the intersection between any two of the sets is an empty set and the union of them is {1, 2, …, 10}. In other (less mathematical) words, choose some groups so each number from 1 to 10 appears exactly once among the chosen groups.

A = {2, 6, 7, 9}

B = {1, 2, 4, 6}

C = {1, 3, 5, 8}

D = {3, 5, 6, 10}

E = {2, 7, 9, 10}

F = {4, 8, 9}

G = {4, 10}
