The answer
The anti-diagonal (top-right to bottom-left) occurs where the sum of the row and column indices equals N + 1 (assuming 1-based indexing).

It is a technique where you generate a full N x N grid and use an if-else statement to determine if the current (row, column) coordinate should contain a star or a blank space.
Use an N x N loop. If the current row is the first or last, OR the current column is the first or last, print a star. Otherwise, print a space.
The main diagonal (top-left to bottom-right) occurs wherever the row index exactly equals the column index (row == col).
