I think the condition that there is one and only one 1 in every row and every column is not necessary since if we have a matrix like:
1 1 1 1 1 1 1 1 1 it is automatically rearrangeable. But I do not have an algorithm for determining whether a matrix is rearrangeable. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
