[Hackerrank] Forming a Magic Square We define a magic square to be an n x n matrix of distinct positive integers from 1 to n2 where the sum of any row, column, or diagonal of length n is always equal to the same number: the magic constant. You will be gicen a 3 x 3 matrix s of integers in the inclusive range [1,9]. We can convert any digit a to any other digit b in the range [1,9] at cost of |a-b|. Given s, convert it into a magic.. 더보기
