// Inverted Full Pyramid Pattern
#include <iostream>
using namespace std;

int main() {
    // Step 1: Declare variable for number of rows
    int rows;

    // Step 2: Prompt user for input
    cout << "Enter the number of rows for the inverted full pyramid: ";
    cin >> rows;

    // Step 3: Outer loop for rows (from rows down to 1)
    for (int i = rows; i >= 1; --i) {
        // Step 4: Inner loop to print leading spaces
        // Number of spaces increases with each row (as i decreases)
        for (int j = 0; j < rows - i; ++j) {
            cout << " ";
        }

        // Step 5: Inner loop to print asterisks
        // Number of asterisks decreases: (2*i - 1)
        for (int k = 1; k <= 2 * i - 1; ++k) {
            cout << "*";
        }
        
        // Step 6: Move to the next line after each row
        cout << endl;
    }
