	        {
	            if(countchar[i] % 2 == 0)f = f - countchar[i];//flag = 1;
	            else f = f - countchar[i] + 1;// flag = 0;
	        }
	        if(f == 0)printf("Yes\n");
	        else printf("No\n");
	    //}
	}
	return 0;

}

My code is working for the given test cases, but it is not working for hidden test cases. Can you help me solve the issue?
