HOLES IN THE TEXT- this gives the correct answer why when i submit it tells me wrong answer

#include “stdio.h”
#include “string.h”

int main()
{

int a,i,j;

    int counter = 0;
    char string [101];

    scanf("%d",&a);

    
    for(i=0;i<a;i++)
    {
            scanf("%s", string);
            for(j = 0; j < strlen (string); j++)
            {
               switch (string[j]){
               
                      case 'A':
                       counter++;
                       break;
                       
                      case 'D':
                       counter++;
                       break;
                       
                      case 'O':
                       counter++;
                       break;
                       
                      case 'P':
                       counter++;
                       break;
                       
                      case 'R':
                       counter++;
                       break;
                       
                      case 'B':
                       counter+=2;;
                       break; 
                       }    
             
            }
            printf("%d\n",counter);
            counter = 0;
    }
	return 0;
}

what about the letter ‘Q’??

You forget the case, when letter is Q. It also has one hole in it.
