![\left[\begin{array}{cccc}1&2&4&3\\2&8&6&4\\-1&4&2&3\end{array}\right]](/tpl/images/0543/6051/e6b83.png)
→ ![\left[\begin{array}{cccc}1&2&4&3\\1&4&3&2\\-1&4&2&3\end{array}\right]](/tpl/images/0543/6051/f51a6.png)
- 
then we have![\left[\begin{array}{cccc}0&-2&1&1\\1&4&3&2\\-1&4&2&3\end{array}\right]](/tpl/images/0543/6051/512e6.png)
thus we have![\left[\begin{array}{cccc}0&-2&1&1\\1&4&3&2\\0&8&5&5\end{array}\right]](/tpl/images/0543/6051/9308c.png)
