@12345limengqi 不是很懂 啥是最后if的地方“不一定是差1”？

by 12345limengqi @ 2023-12-14 12:50:19

    if(e>q)

    printf("%.2lf",e-1);//这不一定差1

    else

    printf("%.2lf",q-1);

    return 0;

}

if(e>q)

    printf("%.2lf",e-1);//不一定是差1
    //应该是次小值和次大值减去平均然后比较 

    else

    printf("%.2lf",q-1);

    return 0;

}
