求助测试点2，就这一个一直不AC

#include <stdio.h>

int main ( )
{
    int a,b,c;
    scanf("%d %d %d",&a,&b,&c);
    if (a<b&&b<c){
        printf("%d/%d",a,c);
    }else if (a<c&&c<b){
        printf("%d/%d",a,b);
    }else if (b<c&&c<a){
        printf("%d/%d",b,a);
    }else if (b<a&&a<c){
        printf("%d/%d",b,c);
    }else if (c<b&&b<a){
        printf("%d/%d",c,a);
    }else if (c<a&&a<b){
        printf("%d/%d",c,b);
    }
    return 0;
}
