Palindromic Numbers problem in C++ but unique (MyLearnings!!)

 #include <iostream>

using namespace std;

/*

MyLearnings:-

1. I lacked visualization for spacing, and should've started from backward to forward which is correct way to do this code

*/

int main() {

    int n = 5;

    // outer loop

    for(int i = 1; i <= n; i++){

        // inner loop

        for(int space = 1; space <= n-i; space++){

            cout << " ";

        }

        // nums backward

        for(int j = i; j >= 1; j--){

            cout << j;

        }

        // nums forward

        for(int j = 2; j <= i; j++){

            cout << j;

        }

        cout << endl;

    }

    return 0;

}

OUTPUT-

1 212 32123 4321234 543212345
