小学生非常讨厌下雨天，特别是有水坑的情况下，由于害怕踩到水里，所以他希望你能帮他算出积水的面积和周长，我们把陆地抽象成为0,1矩阵，0表示陆地，1表示积水，我们把上下左右相连的积水认为是同一块积水，小学生希望算出最大的积水面积和周长。

<span style="font-family:宋体;font-size:16px;">如图</span><span></span> 

<span style="font-size:16px;">0001</span> 

<span style="font-size:16px;">0111</span> 

<span style="font-size:16px;">0010</span> 

<span style="font-size:16px;">0000</span> 

<span style="font-family:宋体;font-size:16px;">最大积水面积为</span><span style="font-size:16px;">5</span><span style="font-family:宋体;font-size:16px;">，最大积水周长为</span><span style="font-size:16px;">12</span>

测试包含多组测试数据

<span style="font-family:宋体;font-size:16px;">第一行输入</span><span style="font-size:16px;">2</span><span style="font-family:宋体;font-size:16px;">个整数</span><span style="font-size:16px;">n,m</span><span style="font-family:宋体;font-size:16px;">，用空格隔开</span><span></span> 

<span><span style="font-size:16px;">1&lt;=n,m&lt;=1000</span><span style="font-size:16px;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </span></span>

<span style="font-family:宋体;font-size:16px;">接下来</span><span style="font-size:16px;">n</span><span style="font-family:宋体;font-size:16px;">行，每行</span><span style="font-size:16px;">m</span><span style="font-family:宋体;font-size:16px;">个</span><span style="font-size:16px;">01</span><span style="font-family:宋体;font-size:16px;">字符</span><span></span> 

对于每组测试数据输出

<span style="font-family:宋体;font-size:16px;">最大积水面积和周长，中间用空格隔开</span><span></span>
