reverse the vector in c++ code example

Example 1: c++ reverse vector

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

int main()
{
    vector<int> nums{4,1,2,1,2};

    reverse(nums.begin(), nums.end());
    return 0;
}

Example 2: reverse a vector

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

Example 3: reverse a vector c++

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

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