my solution :

#include<bits/stdc++.h>
#include
#include
using namespace std;

set claps;

bool haveClapped(long long num)
{
if(claps.count(num))
return false;

claps.insert(num);

if(num%7==0)
    return true;

while(num)
{
    if(num%10==7)
        return true;

    num /= 10;
}
return false;

}

int main()
{
int m,n,k,clapped;
bool decider;
long long currentNum;
clapped=0;
while(scanf(“%d %d %d”,&n,&m,&k) && m)
{
claps.clear();
clapped=0;
currentNum=m;
decider=true;

    while(1)
    {
        if(haveClapped(currentNum))
        {
            cout<<currentNum<<endl;
            clapped++;
        }

        if(clapped==k) break;

        if(decider)
        {
            currentNum += 2*(n-m);
            decider=false;
        }
        else
        {
            currentNum += 2*(m-1);
            decider=true;
        }
    }
    cout<<currentNum<<endl;
}

}
