Who can help me with a code to find duplicates in a vector?

Question

I've always thought of a way to remove the duplicates from a vector, but I found none, can someone help me?

Answer 1

You may use a temporary set to remove duplicates from your vector:

template<class T>
void RemDuplicates(vector<T>& v)
{
set<T> s;
for(int i=0;i<size;++i)
s.insert(vec[i]);
vec.assign(s.begin(),s.end());
}
