Programming Exercise Python:

Magic squares. An n n matrix that is filled with the numbers 1, 2, 3, . . ., n² is a magic square if the sum of the elements in each row, in each column, and in the two diagonals is the same value. Write a program that reads in 16 values from the keyboard and tests whether they form a magic square when put into a 4 4 table. You need to test two features: 1. Does each of the numbers 1, 2, , 16 occur in the user input? 2. When the numbers are put into a square (put the first 4 into the 1st row, second 4 into the 2nd row, and so forth), are the sums of the rows, columns, and diagonals equal to each other?
