问题 I have a string (HTML in this example case) which contains the same pattern for displaying the results of sports games. So, the HTML tags are known, but the values for each game are not. In Perl, we can do this: if ( $content =~ /\<\/a\>\<br\>(\d+)\<\/span\>\<br\>(\d+)\-(\d+).+\<\/a\>\<br\>(\d+)\<\/span\>\<br\>(\d+)\-(\d+)/) { $visitingTeamScore = $1; // $1 is the 1st matched digit $visitingTeamWins = $2; // $2 is the 2nd matched digit $visitingTeamLosses = $3; // Etc $homeTeamScore = $4;

问题 I have a table (>1Mio rows) with string data, from which I need to extract the patterns. That is, if the first row containts the value 'US003TX' it should generate the pattern [A-Z]{2}\d{3}[A-Z{2} If he search finds a new value it should genderate the next pattern. The pattern can be a regex or some pther pattern description.

It is a simple game demo that drops pieces randomly on a 12x10 grid and after each piece drop checks the grid for any groups that are three or more adjacent pieces. I am using the following code in an attempt to do this without flood fill, recursion, or stacks/queues. It seems to almost work, but will destroy squares that are not of the same type sometimes, or leave squares that should be destroyed. So, is the
