We define a magic square to be a 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 given 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|. For this Problem Forming a Magic Square Given s, convert it into a magic square at minimal cost. Print this cost on a new line.Note: The …
