Example: Input Program 3: Java Program to print the Hollow Inverted Mirrored Right Triangle Star Pattern. The number of stars decreases row by row, creating the inverted shape. Hence, we'll have to use 2 loops : one for the upper triangle and the second for the inverse triangle. We have added the compiler to each case with sample outputs citing specific couple hints: first off, for each row, which loop is controlling the maximum value printed? (answer: notice that it's the outer loop that is essentially deciding the max values for each row, because the inner loop depends on the outer one. Sierpinski triangle from Pascal triangle. 4.
