跟P243中有些相似,不直接输出样例的最简

#include<bits/stdc++.h>
using namespace std;
int main()
{
    int n;
    cin>>n;
    int a=n%10,b=n/10%10,c=n/100;
    if (min(min(a,b),c)==0)
        if (max(max(min(a,b),min(a,c)),min(b,c))==0)
            cout<<max(max(a,b),c)*100-max(max(a,b),c);
        else
            cout<<max(max(a,b),c)*100+10*min(min(max(a,b),max(a,c)),max(b,c))-max(max(min(a,b),min(a,c)),min(b,c))*10-max(max(a,b),c);
    else
        cout<<max(max(a,b),c)*100+min(min(max(a,b),max(b,c)),max(a,c))*10+min(min(a,b),c)-min(min(a,b),c)*100-max(max(min(a,b),min(a,c)),min(b,c))*10-max(max(a,b),c);
    return 0;
}
