What is the key to printing a right-angled triangle?
The key is making the inner loop's termination condition dynamically dependent on the outer loop's counter (e.g., col <= row).

The inner loop will lose its dynamic dependency and will always print N stars, resulting in a square instead of a triangle.
Yes, simply replace the print statement. If you print 'col', it will output '1', '12', '123'. If you print 'row', it will output '1', '22', '333'.
It is O(N^2). Even though the inner loop runs fewer times initially, mathematically it executes roughly (N^2)/2 times, which simplifies to O(N^2).
