pick '0' and keep track if we have visited that '0' before a '0' will not surrender if it is on boundary
a '0' is ready to surrender if 1. it is surrounded by no '0' in all 4 directions (easy one) or 2. if it is surrounded by 1 to 4 '0' then it will surrender but we will ask each of the neighbouring '0' . so in this case traverse all neighbouring '0' and ask each one if it is ready to surrender. if all say yes then surrender them all . if even one of them says no, then whole group should not surrender -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
