2021-7: Can You Feel the Magic?
Wikipedia states that, in recreational mathematics, a square array of numbers, usually positive integers, is called a magic square if the sums of the numbers in each row, each column, and both main diagonals are the same.
Write a function to test whether an array is a magic square. The function must:
- have a right argument that is a square matrix of integers (not necessarily all positive integers)
- return 1 if the array represents a magic square, otherwise return 0
💡 Hint: The dyadic transpose X⍉Y function could be helpful for solving this problem.
Examples:
(your_function) 1 1⍴42
1
(your_function) 3 3⍴4 9 2 3 5 7 8 1 6
1
(your_function) 2 2⍴1 2 3 4
0
