#include<iostream>using namespace std;int dec(int i){int sum=0;while(i){sum+=i%10;i=i/10;}//cout<<sum<<endl;return sum;}int duo(int i){int sum=0;while(i){sum+=i%12;i=i/12;}return sum; }int hex(int i){int sum=0;while(i){sum+=i%16;i=i/16;}return sum;}int main(){for(int i=1000;i<=9999;i++){   if(dec(i)==duo(i)&&dec(i)==hex(i))     cout<<i<<endl;}return 0; }
