#### removing duplicate vector from 2d vector

I have coded this to remove similar vector from 2d vector, this can be for any numbers of vector inside 2d vector but for example I have taken only 3 vector.

here, `{1,2,3,4}` is similar to `{3,2,1,4}` so I have to remove `{3,2,1,4}`.

``````#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;

int main()
{
vector<vector<int> > v = { { 1, 2, 3, 4 }, { 5, 6, 7, 8 }, { 3, 2, 1, 4 } };
vector<int> r, c;

// sorting elements
for (auto row = v.begin(); row != v.end(); row++) {
sort(row->begin(), row->end());
}

// Deleting Duplicates
for (auto row = v.begin(); row != v.end() - 1; row++) {
r.clear();
c.clear();
cout << endl
<< endl;
for (auto col = row->begin(); col != row->end(); col++) {
r.push_back(*col);
}

for (auto cr = row + 1; cr != v.end(); cr++) {
for (auto cc = cr->begin(); cc != cr->end(); cc++) {
c.push_back(*cc);
}

if (r == c)
v.erase(cr->begin(), cr->end());
c.clear();
}
cout << endl;
}

// Printing
for (auto row = v.begin(); row != v.end(); row++) {
for (auto col = row->begin(); col != row->end(); col++) {
cout << *col << " ";
}
}
}

``````error: no matching function for call to ‘std::vector >::erase(std::vector::iterator, std::vector::iterator)'
