how to reverse a vector

1#include <bits/stdc++.h> // Vector
2#include <algorithm>  // Reverse 
3using namespace std;

5int main()
6{
7    vector<int> nums{4,1,2,1,2};
8
9    reverse(nums.begin(), nums.end());
10    return 0;

1//vector<int> A;
2reverse(A.begin(),A.end());

1vector<int> a = {1,2,3,4,5,6};
2reverse(a.begin(), a.end());

1//Reverse vector partially (from index x to index y)
2reverse(v.begin()+x, v.begin()+y+1);

1// Given the vector
2vector<int> a = { 1, 45, 54, 71, 76, 12 };

4// Reverse the vector
5reverse(a.begin(), a.end());

1reverse(start_index, last_index);
