Cuperman defines **CS203 Lucky number** as that if you rotate the number 180 degrees the
number will not change. For example, 69, 96, 111, 181 are lucky numbers. 87, 76
are not.(0, 1, 8 will not change in this way, 6 will change into 9, 9 will change into 6. 2 and 5 can't change to each other) Now Cuperman wants to know the number of **CS203 lucky number** between range L and R, so she asked Huang Bo, as
you know, Huang Bo is lazy, he wants you to solve this problem!
