- To print sum of rows|columns|diagonals of an N x N magic matrix
User Input: 3
Output: 15
import java.util.Scanner
fun main(args: Array<String>) {
print("Enter N of N X N magic matrix(must be odd number) :")
val userInput = Scanner(System.`in`)
var n:Int = userInput.nextInt()
print("Sum of rows|columns|diagonals of $n x $n magic matrix : "+ (n*(n*n+1))/2)
}
Enter N of N X N magic matrix(must be odd number) : 5 Sum of rows|columns|diagonals of 5 x 5 magic matrix : 65Program
Remember : Magic matrix are always odd value matrix
like : 3x3,5x5,7x7,.....
So, you must first check it for an Odd value
(n*(n*n+1))/2 //Formula to calculate the sum
To check for odd value
n%2!=0
