Answer to Question #43420 in Programming & Computer Science for balu

Question

Given a square matrix with the elements 0 or 1, write a program to find a maximum square
submatrix whose elements are all 1s. Your program should prompt the user to enter the number
of rows in the matrix. The program then displays the location of the first element in the
maximum square submatrix and the number of the rows in the submatrix. Here is a sample run:
Enter the number of rows in the matrix: 5
Enter the matrix row by row:
10101
11101
10111
10111
10111
The maximum square submatrix is at (2, 2) with size 3
Your program should implement and use the following method to find the maxi- mum square
submatrix:
public static int[] findLargestBlock(int[][] m)
The return value is an array that consists of three values. The first two values are the row and
column indices for the first element in the submatrix, and the third value is the number of the
rows in the submatrix.
