Python Program / Project - 12.

Write a python Program for magic square. A magic square is an n * n matrix of the integers 1 to n2 such that the sum of each row, column, and diagonal is the same. The figure given below is an example of magic square for case n=5. In this example, the common sum is 65.

Programming Language: Python. IDE: Visual Studio Code ( VSC ). Present: go2collage.

Programming Code:

def Magic(s,Size):

    for  i in range(0,size):

        for j in range( 0,size):

            s[i][j] = 0

    nr = 0  

    nc = Size // 2 

    s[nr][nc] = 1

    for  i in range(2,(Size*Size)+1):

        Row = nr

        Col = nc

        nr=nr-1

        if (nr < 0 ):

            nr = Size - 1

        nc=nc-1

        if ( nc < 0 ):

            nc = Size - 1

        if ( s[nr][nc] != 0):

            nr = Row+1

            nc =Col

        s[nr][nc] = i

# Driver Code

size = int(input("Enter the size of the matrix (No. of Rows): "))

row = 0

col = 0

sq = [[0 for col in range(size)] for row in range(size)]

if (size % 2 == 0):

    print("Error, Number of rows/cols should be odd.")

    print("Press any key to terminate.")

    exit()

else:

    Magic(sq, size)

    print("Magic Square is: ")

    for i in range(0, size):

        for j in range(0, size):

            print(sq[i][j], end=" ")

        print()

    sum = 0

    # Displaying the sum

    for j in range(0, size):

        sum = sum + sq[0][j]

    print("\n Sum = ", sum)
