把一个vector里重复的元素给去掉

std::vector<int>& delRepeat(std::vector<int>& nVector)
{
	std::set<int> nTemp(nVector.begin(),nVector.end());

	nVector.clear();

	for (std::set<int>::iterator nIterator = nTemp.begin();nIterator != nTemp.end();nIterator++)
		nVector.push_back(*nIterator);

	return nVector;
}

std::vector<int>& delRepeat(std::vector<int>& nVector)
{
    std::vector<int> nTemp(nVector.begin(),nVector.end());
    nVector.clear();
    for (std::vector<int>::iterator nIterator = nTemp.begin();nIterator != nTemp.end();nIterator++)
    {
        if(std::find(nVector.begin(),nVector.end(),*nIterator) != nVector.end())
        nVector.push_back(*nIterator);
    }
    return nVector;
}
