Character recognition is the conversion of images into text. For now we consider each
character in the picture is a N*M matrix with only zeros and ones, and we need to
recognize K characters. You are to write a program to find minimal number of pixels so
that we can recognize each character.
For example, we have only two characters ‘T’ and ‘L’, and the matrix size is 3*3, we
can think ‘T’ and ‘L’ are
The first line of input is three integers N, M, K (1 <= N, M <= 10, 2 <= K <= 6).
Which represents the size of matrix and number of characters. Then is following K
blocks, which represents the matrix. Notice that each block starts with a blank
You should output the minimum number of pixels, which is the answer.
