CodeGraderBench/CodeGraderBench huggingface dataset:
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; //number of rows
    cin>>n;
    for (int i=1;i<=n;i++){ //i indicates which row we are on
        for (int space=i;space>1;space--){ //number of spaces for ith row
            cout<<" ";
        }
        for (int j=1;j<=(n+1-i);j++){
            ((j%2)==0)? cout<<"X" : cout<<"O"; //alternate printing using ternary operator and divisibility of column by 2
        }

Problem: A multinational company wants to form a team consisting of two programmers for an upcoming project. The team selection depends on three distinct skills:

1. New Code
2. Debugging
3. Optimizing

Each programmer has a value of either 0 or 1 for each skill:
- 1 indicates the programmer is skilled in that area.
- 0 indicates the programmer is not skilled in that area.

Compatibility Condition:

Two programmers A and B are considered compatible if all the following conditions are satisfied:

1. Both programmers must be good at new code.
   (Both A and B must have a value of 1 for "new code".)

2. At least one programmer must be good at debugging.
   (Either A or B must have a value of 1 for "debugging".)

3. At least one programmer must be good at optimizing.
   (Either A or B must have a value of 1 for "optimizing".)

Write a C++ program to take the skill values of two programmers as input and determine whether they are compatible.

If they are compatible, print:
compatible

Otherwise, print:
not compatible

Note:
- Output must be in lowercase.
- Do not print any extra messages or prompts.

Input:
Six integers representing the skills of two programmers:
A_new A_debug A_opt B_new B_debug B_opt

Output:
Print "compatible" if conditions are satisfied, otherwise print "not compatible".

Student submission:
#include <simplecpp>

Each programmer has a value of either 0 or 1 for each skill:
- 1 indicates the programmer is skilled in that area.
- 0 indicates the programmer is not skilled in that area.

Compatibility Condition:

Two programmers A and B are considered compatible if all the following conditions are satisfied:

1. Both programmers must be good at new code.
   (Both A and B must have a value of 1 for "new code".)

2. At least one programmer must be good at debugging.
   (Either A or B must have a value of 1 for "debugging".)

3. At least one programmer must be good at optimizing.
   (Either A or B must have a value of 1 for "optimizing".)

Write a C++ program to take the skill values of two programmers as input and determine whether they are compatible.

If they are compatible, print:
compatible

Otherwise, print:
not compatible

Note:
- Output must be in lowercase.
- Do not print any extra messages or prompts.

Input:
Six integers representing the skills of two programmers:
A_new A_debug A_opt B_new B_debug B_opt

Output:
Print "compatible" if conditions are satisfied, otherwise print "not compatible".

Student submission:
#include<simplecpp>
main_program{
        bool cd1,dbug1,opt1;
        bool cd2,dbug2,opt2;
        cin>> cd1>>dbug1>>opt1;
        cin>> cd2>>dbug2>>opt2;
        if((cd1 && cd2) && (dbug1 || dbug2) && (opt1 || opt2)){
                cout << "compatible";
        }
        else{
                cout << "not compatible";
        }
}
