(x) (2) with the upper and lower parenthesis concatenated to a big parenthesis, what math does this notation mean? I think there may have two, one is 2^x, another is "select 2 elements from x, with the order, how many combination the selection has".
Which one is common? Thanks. Bin --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
