We know that this disease is contagious and anyone affected comes in contact with another person, then he or she needs to stay in quarantine. Suppose an educational institution "X" has hired you to design a system known as an "Infected tracker". An infected tracker tries to figure out the region/number of surrounding people who can be affected by a single person. Then it prints the maximum region infected. Here you can consider Y being infected and N is not infected. Your task is to find the maximum region with Y i.e. max people infected in a region so that strict measures can be taken in that region. Keep in mind that two people are said to be infected if two elements in the matrix are Y horizontally, vertically or diagonally. Sample Input 1 NNNYYNN NYΝNYΥΝ ΥYNYNNY. NNNNNYN ΥYNNNN NNNYNNN Sample Output 7
