Help with vector search

Andrewcen16 (35)

I do not know what to do from here i keep getting errors in visual studio
Also i am ignoring the multiplicities part at the moment

Write a predicate function
bool same_set(vector<int> a, vector<int> b)
that checks whether two vectors have the same elements in some order, ignoring
multiplicities. For example, the two vectors

1 4 9 16 9 7 4 9 11
11 11 7 9 16 4 1

would be considered identical. You will probably need one or more helper
functions.

isNum is always "false" -> your code is entrappt in an eternal loop!

one of the simplest debugging techniques is to log information!

cout << _FUNC_ << " " << _LINE_ << " : " << "counter: " << counter << endl;

The lack of information is the problem which makes one unable to solve it.
