Answer 1

这题，小学的知识无法算出，加减乘除不行
高中知识lg10=1
变成
3
4
1
11
((3*4)+1)+11
(3*4)+(1+11)
((3*4)+11)+1
(3*4)+(11+1)
3*(1-(4-11))
3*((1-4)+11)
3*((1+11)-4)
3*(1+(11-4))
3*(11-(4-1))
3*((11-4)+1)
(3-11)*(1-4)
3*((11+1)-4)
3*(11+(1-4))
((4*3)+1)+11
(4*3)+(1+11)
((4*3)+11)+1
(4*3)+(11+1)
(4-1)*(11-3)
1+((3*4)+11)
(1+(3*4))+11
(1-4)*(3-11)
1+((4*3)+11)
(1+(4*3))+11
(1-(4-11))*3
((1-4)+11)*3
1+(11+(3*4))
(1+11)+(3*4)
((1+11)-4)*3
(1+(11-4))*3
1+(11+(4*3))
(1+11)+(4*3)
(11-3)*(4-1)
11+((3*4)+1)
(11+(3*4))+1
11+((4*3)+1)
(11+(4*3))+1
(11-(4-1))*3
((11-4)+1)*3
11+(1+(3*4))
(11+1)+(3*4)
((11+1)-4)*3
(11+(1-4))*3
11+(1+(4*3))
(11+1)+(4*3)
