Codeforces Round #535 (Div. 3) a题
http://codeforces.com/contest/1108/problem/A
题解:一段数轴上四个点,l1,r1,l2,r2,分别在l1,r1取一点,在l2,r2中取一点
#include <bits/stdc++.h>
using namespace std;
int main(){
int t;
cin >> t;
while(t--){
int l1,r1,l2,r2;
cin >> l1 >> r1 >> l2 >> r2;
vector<int>a({l1,r1,l2,r2}); //容器,压缩
int ans1 = 0,ans2 = 0;
for(auto it :a)for(auto jt : a){
if( l1 <= it && it <= r1 && l2 <= jt && jt <= r2 && it != jt)
{
ans1 = it;
ans2 = jt;
}
}
cout << ans1 << " " << ans2 << endl;
}
return 0;
}
for(auto &a:str)就相当于for循环 &a就相当于int i=0;,遍历数组str
