./cs512/c++/cppdef/dsa.cpp:175: error: no matching function for callto

Hi I have the following error.
../cs512/c++/cppdef/dsa.cpp:175: error: no matching function for call
to 'str_to_numlist(std::back_insert_iterator<std::vector<BigInteger,
std::allocator<BigInteger> > >, const std::basic_string<char,
std::char_traits<char>, std::allocator<char> >&, const BigInteger&)'

Here is the codes

/****************************************************

What is wrong?

Hi I have the following error.

Are you sure that the 'value_type' type of 'back_insert_iterator'
is the same as 'BigInteger'?

Not sure. Can you distill it to a simple sample without all the
namespaces and BigIntegers?
