@wrk20111205 闰年判断不对

#include<bits/stdc++.h>

using namespace std;

bool r(long long i){

    if(i%4==0 && i%100!=0 || i%400==0 && i%3200!=0) return 1;

    else return 0;

}

int main()

{

    ios::sync_with_stdio(false);

    cin.tie(0), cout.tie(0);

    long long x,y,a=0;

    cin>>x>>y;

    for(int i=x;i<=y;++i){

        if(r(i)) a++;

    }

    cout<<a<<endl;

    for(int j=x;j<=y;++j){

        if(r(j)) cout<<j<<" ";

    }

    return 0;

}
