Help me in solving STAR problem

My issue

The code is executed successfully but can’t submit it

My code

#include <bits/stdc++.h>
using namespace std;
#include<iostream>
int main() {
	// your code goes here
	int n;
	std::cin >> n;
   // Upper triangle
    for (int i = 1; i <= n; i++) {
        // Print spaces
        for (int j = i; j < n; j++) {
            cout << " ";
        }
        // Print stars
        for (int j = 1; j <= (2 * i - 1); j++) {
            cout << "*";
        }
        cout << endl;
    }
    // Lower triangle
    for (int i = n - 1; i >= 1; i--) {
        // Print spaces
        for (int j = n; j > i; j--) {
            cout << " ";
        }
        // Print stars
        for (int j = 1; j <= (2 * i - 1); j++) {
            cout << "*";
        }
        cout << endl;
    }
}
