三位数重新排列

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

    千钱买千鸡

    #include<bits/stdc++.h>
    using namespace std;
    int main(){
    	int a,b,c,d;
    	cin>>a>>b>>c>>d;
    	for(int i=0;i<=1000/a;i++) {
    		for(int j=0;j<=1000/b;j++) {
    			for(int k=0;k<=1000/c;k++) {
    				int l=1000-i-k-j;
    				if(l+i+j+k==1000&&i*a+j*b+k*c+l*1.0/d==1000){
    					cout<<i<<' '<<j<<' '<<k<<' '<<l;
    					return 0;
    				}
    			}
    		}
    	}
    	cout<<"-i";
    	return 0;
    }
