Downward triangle star pattern means we want to print a triangle that is downward facing means base is upwards and by default, orientation is leftwards so the desired triangle to be printed should look like

Example

Java




// Java Program to Print Lower Star Triangle Pattern
 
// Main class
public class GFG {
 
    // Main driver method
    public static void main(String[] args)
    {
        // Nested 2 for loops for iteration over the matrix
 
        // Outer loop for rows
        int rows = 9;
        for (int a = rows - 1; a >= 0; a--) {
 
            // Inner loop for columns
            for (int b = 0; b <= a; b++) {
 
                // Prints star and space
                System.out.print("*"
                                 + " ");
            }
 
            // By now we are done with single row so new
            // line
            System.out.println();
        }
    }
}

Output

* * * * * * * * * 
* * * * * * * *

Time Complexity: O(n2), where n represents the given number of rows.
Auxiliary Space: O(1), no extra space is required, so it is a constant.
