Day 6: The Connected Cell in a Grid
You are given a matrix with rows and columns of cells, each of which contains either or . Two cells are said to be connected if they are adjacent to each other horizontally, vertically, or diagonally. The connected and filled (i.e. cells that contain a ) cells form a region. There may be several regions in the matrix. Find the number of cells in the largest region in the matrix.
Input Format
There will be three parts of t input:
The first line will contain , the number of rows in the matrix.
The second line will contain , the number of columns in the matrix.
This will be followed by the matrix grid: the list of numbers that make up the matrix.
Output Format
Print the length of the largest region in the given matrix.
