有如下程序,若输入a=23,b=17,c=19,那么输出结果为()#includeintmain(){intdif(intx,inty,intz);inta,b,c,d;scanf("%d%d%d",&a,&b,&c);d=dif(a,b,c);printf("Max-Min=%d",d);return0;}intdif(intx,inty,intz){intmax(intx,inty,intz);intmin(intx,inty,intz);returnmax(x,y,z)-min(x,y,z);}intmax(intx,inty,intz){intr,c;r=x>y?x:y;c=r>z?r:z;returnc;}intmin(intx,inty,intz){intr,c;r=x
