What are the rules of magic square?

A magic square is a grid of numbers arranged such that the sum of each row, column, and both main diagonals is the same, known as the magic constant. In a standard n x n magic square, this constant can be calculated using the formula (M = \frac{n(n^2 + 1)}{2}). Each number in the square must be unique and typically consists of the integers from 1 to (n^2). The arrangement must ensure that all sums are equal, creating a balanced and harmonious layout.
