    Here is my solution!

    #include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;


int main() {
    ios::sync_with_stdio(false);
    cin.tie(0);
    int size, index, start_index, end_index;
    cin >> size;
    vector<int> ints(size, 0);
    for (int i = 0; i < size; i++) {
        cin >> ints.at(i);
    }
    cin >> index >> start_index >> end_index;
    ints.erase(ints.begin() + index - 1);
    ints.erase(ints.begin() + start_index - 1, ints.begin() + end_index - 1);
    cout << ints.size() << "\n";
    for (int integer : ints) {
        cout << integer << " ";
    }
    return 0;
}

    int main() { /* Enter your code here. Read input from STDIN. Print output to STDOUT */
    int n; cin >> n; // vecot declare... vector v (n); // element input.. for(int i = 0; i < v.size(); i++) { cin >> v[i]; } int pos; cin >> pos; // delete element 4 (index-2) v.erase(v.begin() + (pos - 1)); int a, b; cin >> a >> b; // range delete 2 to 4 v.erase(v.begin() + (a-1), v.begin() + (b-1)); cout << v.size() << endl; for(int p: v) { cout << p << " "; } cout << endl; return 0; }

    #include <iostream>
#include <vector>

using namespace std;

int indexify(int i)
{
    return --i;
}

int main()
{
    int n;
    cin >> n;

    vector<int> numbers;

    while (n > 0)
    {
        int number;
        cin >> number;
        numbers.push_back(number);
        n--;
    }

    int element_nr;
    cin >> element_nr;

    numbers.erase(numbers.begin() + indexify(element_nr));

    int start, end;
    cin >> start >> end;

    numbers.erase(numbers.begin() + indexify(start), numbers.begin() + indexify(end));

    cout << numbers.size() << endl;
    for (int i = 0; i < numbers.size(); i++)
        cout << numbers[i] << " ";
}
