Run an outer loop (i) from 0 to N-1 for rows.

For each row, run an inner loop (j) starting from N down to i+1.

Print a star (*) in each iteration of the inner loop.

After finishing each row, print a newline to move to the next row.

Code

#include <bits/stdc++.h>
using namespace std;

class Solution {
public:
    // Function to print Pattern 5
    void pattern5(int N) {
        // Outer loop for rows
        for (int i = 0; i < N; i++) {
            // Inner loop for columns
            // Number of stars decreases with each row
            for (int j = N; j > i; j--) {
                cout << "* ";
            }
            // Move to next line
            cout << endl;
        }
    }
};

int main() {
    // Create object of Solution class
    Solution sol;

    // Define size of pattern
    int N = 5;

    // Call pattern function
    sol.pattern5(N);

    return 0;
