My issue

i can’t solve this problem

My code

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

int main() {
    int N;
    cin >> N;

    // Upper Half
    for (int i = 0; i < N; i++) {
        // Left stars
        for (int j = 0; j < N - i; j++) {
            cout << "*";
        }
        // Spaces in the middle
        for (int j = 0; j < 2 * i; j++) {
            cout << " ";
        }
        // Right stars
        for (int j = 0; j < N - i; j++) {
            cout << "*";
        }
        cout << endl;
    }

    // Lower Half
    for (int i = 0; i < N; i++) {
        // Left stars
        for (int j = 0; j <= i; j++) {
            cout << "*";
        }
        // Spaces in the middle
        for (int j = 0; j < 2 * (N - i - 1); j++) {
            cout << " ";
        }
        // Right stars
        for (int j = 0; j <= i; j++) {
            cout << "*";
        }
        cout << endl;
