ICHB Selection Contest '17 Problem 2 - Black Star's Visit
View as PDFBlack Star hates people that are not symmetrical. He defines symmetry for numbers as either horizontal symmetry (each digit, when cut in half horizontally, must have the same upper half as lower half), or vertical symmetry (when cutting the number at the middle digit/digits, the  digit from the half towards the start must be equal to the 
 digit from the half towards the end). Each city in his country is indexed from 
 to 
, and for a city 
 its citizens are numbered from 
 to 
 (all the natural numbers of 
 digits). Furthermore, we know that Black Star will visit 
 cities out of the 
, and for each of them he wants to know how many people in that city he hates. However, since the number is pretty large, he asks us the number 
. Since we also have other tasks at hand given by Black Star, we ask you to give us the answer for the 
 cities.
