75分求救，代码可能有些抽象

#include<bits/stdc++.h>
using namespace std;
long long a,b,c,a1,a2,cc,aa,bb,abc,abcd;
int main(){
	cin>>a>>b>>c;	
	if(a+b<c){
		a1=c;
		a2=a+b;
	}
	else if(a+b>c){
		cc=a+b-c;
		aa=a+c-b;
		bb=b+c-a;
		abc=min(cc,aa);
		abcd=min(abc,bb);
		if(abcd==cc){
			a1=a+b;
			a2=c;
		}
		if(abcd==aa){
			a1=a+c;
			a2=b;
		}
		if(abcd==bb){
			a1=c+b;
			a2=a;
		}
	}
	cout<<a1<<" "<<a2;
	return 0;
}
