Extra Long Factorials

  • viigihabe + 0 comments

    Looked down at the link "Environment". C++ developers have Boost in their hands. So it boils down to:

    #include <boost/multiprecision/cpp_int.hpp>
// Complete the extraLongFactorials function below.
void extraLongFactorials(int n) {
    using boost::multiprecision::cpp_int;
    int multiplier = 1;  
    cpp_int factorial = 1;
    while(multiplier <= n)
        factorial *= multiplier++;
    cout << factorial;
}

    My comment doesn't have any algorithmical value but it might direct to right direction. Don't invent the wheel when someone has done it allready.
