#include <iostream>
#include <vector>

int main() {
    std::vector<int> nums = {1, 2, 3, 4, 5};

    // Method 1: Using negative index
    int lastElem1 = nums[nums.size() - 1];

    // Method 2: Using back() function
    int lastElem2 = nums.back();

    std::cout << "Last element (Method 1): " << lastElem1 << std::endl;
    std::cout << "Last element (Method 2): " << lastElem2 << std::endl;

    return 0;
