1. B = 4個數值
   1. 3
   2. 5
   3. 7
   4. 8
2. A = 8個數值
   1. 1
   2. 2
   3. 3
   4. 4
   5. 5
   6. 6
   7. 2
   8. 3
3. A與B合併再排序 = 12個數值
   1. 1
   2. 2
   3. 2
   4. 3
   5. 3
   6. 3
   7. 4
   8. 5
   9. 5
   10. 6
   11. 7
   12. 8
4. 去除重複筆數後得出A＋B數列 = 8個數值
   1. 1
   2. 2
   3. 3
   4. 4
   5. 5
   6. 6
   7. 7
   8. 8
5. A與B重複數字 = 2個數值
   1. 3
   2. 5
6. A本身重複數字=2個數值
   1. 2
   2. 3
7. 不考慮數列本身重複的數值
   1. Remove duplication ( Sort ( 8 + 4 ) ) = 8
   2. Repeat ( A & B ) = 12 - 8 = 4
8. 考慮數列本身重複的數值
   1. Remove A duplication ( Sort ( A ) ) = 6
   2. Remove duplication ( Sort ( 6 + 4 ) ) = 8
   3. Repeat ( A & B ) = 10 - 8 = 2
