I don't know what you mean by this picture! The premise is that 1 to 10 is not reused! If the sum of only one number in the first line is 10, then only 10 can be added, and the sum of two numbers in the fourth line is 10, it must be 9+ 1= 10, because if there is 9 in the second line and the third line, then 9 plus any two noes. Eight plus any two numbers is greater than 10, and eight plus any three numbers is also greater than 10. So 8 has no solution. Because the previous answer is unique, there is no solution to this problem without my understanding of the right and wrong questions. I guess your question is wrong! Please check back before asking questions!
