If the outer loop runs from 1 to N, the number of stars per row is N - row + 1.
Reversing the outer loop (starting from N and decrementing) is usually much cleaner and easier to read, reducing the chance of off-by-one math errors.
Use the same loop structure, but inside the inner loop, print the variable 'col' (for 1234, 123) or 'row' (for 4444, 333).
