SOLUTION CODE

# PYTHON

class Solution(object):
    def getConcatenation(self, nums):
        """
        :type nums: List[int]
        :rtype: List[int]
        """
        res = nums

        for i in range(len(nums)):
            res.append(nums[i])
        return res

# C++

class Solution {
public:
    vector<int> getConcatenation(vector<int>& nums) {
        nums.insert(nums.end(),nums.begin(),nums.end());
        return nums;
    }
};
