<section id="description">对于整数m，n（0≤n<m），令L（m，n）为m×m网格，其中右上n×n网格被移除。 <p>例如，L（5,3）看起来像这样： </p><p>我们希望用连续的整数1,2,3 ......对L（m，n）的每个单元进行编号，使得每个单元格中的数字小于它下面和左边的数字。 </p><p>例如，这里有两个有效的L（5,3）编号： </p><p>设LC（m，n）为L（m，n）的有效编号。可以证实LC（3,0）= 42，LC（5,3）= 250250，LC（6,3）= 406029023400和LC（10,5）mod 76543217 = 61251715。 </p><p>找到LC（10000,5000）mod 76543217。 </p></section>
