Problem: You are required to write a C++ program that prints a right-aligned pattern using the uppercase characters O and X.

Each row of the pattern must follow these rules:

1. The pattern consists of n rows.
2. The first row contains n characters, and each next row contains one less character than the previous row.
3. Every row must start with the character O.
4. The characters must alternate between O and X (O X O X ...).
5. The pattern must be right-aligned, meaning each row is preceded by spaces so that the last characters line up vertically.
6. There must be no spaces between O and X characters.
7. Only print the pattern. Do not print any extra messages, prompts, or labels.

Input:
An integer n representing the number of rows.

Output:
Print the right-aligned alternating pattern of O and X.

Example:

Input:
5

Output:
OXOXO
 OXOX
  OXO
   OX
    O

Important Notes:
- Do not print messages like "Enter a number" or "The output is".
- Use cout only to print the pattern.
- Do not hard-code the output.
- Do not add extra spaces except those needed for right alignment.

Problem: You are required to write a C++ program that prints a right-aligned pattern using the uppercase characters O and X.

Each row of the pattern must follow these rules:

1. The pattern consists of n rows.
2. The first row contains n characters, and each next row contains one less character than the previous row.
3. Every row must start with the character O.
4. The characters must alternate between O and X (O X O X ...).
5. The pattern must be right-aligned, meaning each row is preceded by spaces so that the last characters line up vertically.
6. There must be no spaces between O and X characters.
7. Only print the pattern. Do not print any extra messages, prompts, or labels.

Input:
An integer n representing the number of rows.

Output:
Print the right-aligned alternating pattern of O and X.

Example:

Input:
5

Output:
OXOXO
 OXOX
  OXO
   OX
    O

Important Notes:
- Do not print messages like "Enter a number" or "The output is".
- Use cout only to print the pattern.
- Do not hard-code the output.
- Do not add extra spaces except those needed for right alignment.

Student submission:
#include<simplecpp>

main_program{
    int n;
    cin>>n;
    for(int i =0 ; i<n ; i++){
        for(int space =0 ; space<i; space++){
            cout<<" ";
        }
        for(int j = n ; j>i ; j--)
        {
            if(n % 2==1){
                if(j % 2 == 1 ){
                cout<<"O";
            }else{
                cout<<"X";
            }
            }else{
                if(j % 2 == 1 ){
                cout<<"X";
            }else{
                cout<<"O";
            }
            }
        }
        cout<<endl;

    }
}
