Pattern Breakdown
Outer Loop (Rows):
The pattern has 9 rows in total.
The first half (rows 1 to 5) increases the number of stars, and the second half (rows 6 to 9) decreases the number of stars.
First Part (Increasing Stars):
The first 5 rows (1st to 5th) contain an increasing number of stars, starting from 1 star and increasing by 1 each time.
Second Part (Decreasing Stars):
The next 4 rows (6th to 9th) contain a decreasing number of stars, starting from 5 stars and reducing by 1 each time.

public class Main { public static void main(String[] args) { int total_rows = 5; // Half of the total rows (excluding the middle row) // First half (increasing stars) for (int row = 0; row < total_rows; row++) { // Print stars for (int star = 0; star <= row; star++) { System.out.print("*"); } System.out.println(); } // Second half (decreasing stars) for (int row = total_rows; row >= 1; row--) { // Print stars for (int star = 0; star < row; star++) { System.out.print("*"); } System.out.println(); } } } |
| C++ |
#include <iostream> using namespace std; int main() { int total_rows = 5; // Half of the total rows (excluding the middle row) // First half (increasing stars) for (int row = 0; row < total_rows; row++) { // Print stars for (int star = 0; star <= row; star++) { cout << "*"; } cout << endl; } // Second half (decreasing stars) for (int row = total_rows; row >= 1; row--) { // Print stars for (int star = 0; star < row; star++) { cout << "*"; } cout << endl; } return 0; } |
| Python |
total_rows = 5 # Half of the total rows (excluding the middle row) # First half (increasing stars) for row in range(total_rows): # Print stars for star in range(row + 1): print("*", end="") print() # Second half (decreasing stars) for row in range(total_rows, 0, -1): # Print stars for star in range(row): print("*", end="") print() |
