    long long decimal, tempDecimal, binary;

    int rem, place = 1;

    binary = 0;

    scanf("%lld", &decimal);

    tempDecimal = decimal;

    while(tempDecimal > 0)

    {

        rem = tempDecimal % 2;

        binary = (rem * place) + binary;

        tempDecimal /= 2;

        place *= 10;
