Siamese construction for odd-order magic squares: - place 1 at (0, n/2) - for k = 2..n^2, move up-right with (x-1+n) mod n wrap - if the target cell is taken, drop down one row instead for n=5, magic constant = n*(n^2+1)/2 = 5*26/2 = 65 Returns the main-diagonal sum (65 by construction). Tests 2D array via Array.init + Array.make, mod arithmetic with the (x-1+n) mod n idiom for negative-safe wrap, nested begin/end branches inside for-loop body. 166 baseline programs total.
