Error in CLEANUP

My solution to the question with code CLEANUP works well for all the public cases, and all other cases I have tried. However, when I submit it, it shows Wrong Answer. Please help me here!

    #include   
    #include 
    

    using namespace std;

    int main() {
	int t;
	cin >> t;
	for(int i = 0; i < t ; i++)
    {
        int n , m, doer = 0;
        cin >> n >> m;

        char jobs[n+1];

        int jdone = 0;

        //storing the jobs done
        for(int j = 0; j < m ; j++ )
        {
            cin >> jdone;
            jobs[jdone] = 'd';
        }

        //storing which jobs chef and which the assisstant will do
        for(int k = 1; k < n+1 ; k++)
        {
            if(jobs[k] == 'd')
                continue;
            else
            {
                if(doer % 2 == 0)
                {
                    jobs[k] = 'c';
                }
                else
                    jobs[k] = 'a';

                doer++;
            }
        }

        //printing out chef's jobs
        for(int l = 1; l < n+1; l++)
        {
            if(jobs[l] == 'c')
            {
                cout << l << " " ;
            }
        }

        cout << endl;

        //printing out assisstant;s jobs
        for(int l2 = 0; l2 < n+1; l2++)
        {
            if(jobs[l2] == 'a')
            {
                cout << l2 << " " ;
            }
        }

        cout << endl;
    }



	return 0;
}

Start the last for loop from 1.(assistant’s jobs).

Intially fill the array jobs[] with some other character(‘X’).
You can see my approach here.
