    Here is my c++ solution, you can watch the explanatoin here : https://youtu.be/xFqneyHR96g

    void printArr(vector<int> arr){
    for(int i = 0; i < arr.size(); i++){cout << arr[i] << " ";}
    cout << endl;
}
void insertionSort1(int n, vector<int> arr) {
    int last = arr[arr.size()-1];
    for(int i = arr.size() - 1; i >= 0; i--){
        if(last < arr[i-1]) {
            arr[i] = arr[i-1];
            printArr(arr);
        }
        else{
            arr[i] = last;
            printArr(arr);
            break;
        }
    }
}

    JAVA int key = arr.get(n - 1); int j = n - 2; 

        while (j >= 0 && arr.get(j) > key) {
        arr.set(j + 1, arr.get(j)); 
        j--; 
        for (int k = 0; k < arr.size(); k++) {
        System.out.print(arr.get(k) + " ");
    }
    System.out.println();
    }

    arr.set(j + 1, key);

      for(int i=0;i<arr.size();i++) {
     System.out.print(arr.get(i) + " ");
 }

    C# Solution

    public static void insertionSort1(int n, List<int> arr)
{
    var last = arr[n - 1];

    for (int i = n - 1; i >= 0; i--)
    {
        if (i == 0 || last > arr[i - 1])
        {
            arr[i] = last;
            Console.WriteLine(string.Join(" ", arr));
            break;
        }
        else
        {
            arr[i] = arr[i - 1];
            Console.WriteLine(string.Join(" ", arr));
        }
    }
}
