A regular expression (shortened as regex or regexp), [1] sometimes referred to as rational expression, [2] [3] is a sequence of characters that specifies a match pattern in text. Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on strings , or for input validation .
This happens when a regular expression has three properties: the regular expression applies repetition (+, *) to a subexpression; the subexpression can match the same input in multiple ways, or the subexpression can match an input string which is a prefix of a longer possible match;
To display the matches for a specific table, set |matches#=yes, replacing # with the sequential number of the relevant table. To display the matches for all the tables, set |matches=yes. If |matches=yes is set, but you wish to hide the matches for a specific table, set |matches#=no, replacing # with the sequential number of the relevant table.
Table tennis is among the sports contested at the Summer Olympic Games. It was introduced at the 1988 Summer Olympics in Seoul, South Korea, where singles and doubles tournaments were held for both genders. [1] The men's and women's doubles events were dropped from the 2008 Summer Olympics program and replaced by team events. [2]
In computer science, an algorithm for matching wildcards (also known as globbing) is useful in comparing text strings that may contain wildcard syntax. [1] Common uses of these algorithms include command-line interfaces, e.g. the Bourne shell [2] or Microsoft Windows command-line [3] or text editor or file manager, as well as the interfaces for some search engines [4] and databases. [5]
Lots are drawn to decide who starts serving in table tennis, and this player will also start serving in squash. The winner of a racketlon match is the player or doubles pair who has won the most points in total. When a player leads a match with more points than there are points left for the opponent to obtain, the match is over.
As an ad hoc sandbox, you can show the wikitext of a section like this, (already saved in the database), modify some of the patterns in the regex-search-link template calls on this page, do a Show Preview, and see what matches when you click on the newly formed regex search-link, all quite safely, and without changing a thing in the database.
