Solution
#include <iostream>
#include<algorithm>
using namespace std;
int main(){
int n;
cin >> n;
bool neg =false;
if(n<0){
neg = true;
n=abs(n);
}
string s=" ";
while(n>0){
int rem=n%7;
s.append(to_string(rem));
n=n/7;
}
if(neg){
s.append("-");
reverse(s.begin(),s.end());
}
cout<<s;
return 0;
}
}
