// Inverted Right-Angled Number Pyramid
import java.util.Scanner;

// Main class containing the entry point of the program
public class Main {
    public static void main(String[] args) {
        // Step 1: Initialize Scanner for user input
        Scanner scanner = new Scanner(System.in);

        // Step 2: Prompt user for the number of rows
        System.out.print("Enter the number of rows for the inverted pyramid: ");
        int rows = scanner.nextInt();

        // Step 3: Outer loop for the number of rows (descending)
        for (int i = rows; i >= 1; i--) {
            // Step 4: Inner loop to print numbers in each row
            for (int j = 1; j <= i; j++) {
                System.out.print(j + " "); // Print number and a space
            }
            System.out.println(); // Move to the next line after each row
        }

        // Step 5: Close the scanner
        scanner.close();
    }
