Problem Statement

Produce a zig-zag array.

A   zig-zag   array is a square arrangement of the first   N2   natural numbers,   where the
numbers increase sequentially as you zig-zag along the array's   anti-diagonals. For a graphical representation, see   JPG zigzag   (JPG uses such arrays to encode images).

For example, given   5,   produce this array:

Let's start with the solution:

Size = 5
DIM array(Size-1, Size-1)

i = 1
j = 1
FOR e = 0 TO Size^2-1
  array(i-1, j-1) = e
  IF and((i + j), 1) = 0 THEN
    IF j < Size then j = j + 1 ELSE i = i + 2 end if
    IF i > 1 i = i - 1
  ELSE
    IF i < Size then i = i + 1 ELSE j = j + 2 end if
    IF j > 1 j = j - 1
  ENDIF
NEXT e

FOR row = 0 TO Size-1
  FOR col = 0 TO Size-1
    PRINT array(row,col) USING "##";
  NEXT col
  PRINT
NEXT row
