/*
Template function to Remove Duplicates
From a vector */

template <class T>
void RemoveDuplicates(vector<T> &vecContents)
{
    vector<T> ::iterator vItr;
  
    sort(vecContents.begin(),vecContents.end());
    vItr=unique(vecContents.begin(),vecContents.end());   
    if(vItr!=vecContents.end())
         vecContents.erase(vItr,vecContents.end());
}




//Usage Example 1

vector<CString> vNames; 
vNames.push_back("John");
vNames.push_back("Victor");
vNames.push_back("Nancy"); 
vNames.push_back("William");
vNames.push_back("Nancy");

RemoveDuplicates(vNames); 


//Usage Example 2
vector<int> vNos;   
vNos.push_back(1);
vNos.push_back(1);
vNos.push_back(4);

RemoveDuplicates(vNos);
