1008B Codeforces - Turn the rectangles

Solution in c++

#include <bits/stdc++.h>

using namespace std;

string it="YES";

int n,t1,t2;

vector<pair<int,int> > all;

int main()

{

    ios::sync_with_stdio(0);

    cin.tie(0);cout.tie(0);

    cin>>n;

    for(int i=0;i<n;i++)

    {

        cin>>t1>>t2;

        all.push_back(make_pair(t1,t2));

        if(i>0)

        {

            if(t1<=all[i-1].second && t2<=all[i-1].second )all[i].second=max(t1,t2);

            else if(t2<=all[i-1].second && t1>all[i-1].second)all[i].second=t2;

            else if(t1<=all[i-1].second && t2>all[i-1].second)all[i].second=t1;

            else it="NO";

        }

        else all[0].second=max(t1,t2);

    }

    cout<<it;

    return 0;

}
