Magic Square

 # Write A Python Program For Magic Square.

# A Magic Square Is An n x n Matrix Of The Integers 1 to n^2 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 Example, The Common Sum Is 65.

#                                [[  9.  3. 22. 16. 15.]
