contains

Just had an interesting argument in the comment to one of my questions. My opponent claims that the statement "" does not contain "" is wrong. My reasoning is that if "" contained another "" , that one would also contain "" and so on. Who is wrong? P.S. I am talking about a std::string P.S. P.S I was not talking about substrings, but even if I add to my question " as a substring", it still makes no sense. An empty substring is nonsense . If you allow empty substrings to be contained in strings, that means you have an infinity of empty substrings. What is the point of that? Edit: Am I the only

Problem: The radius parameter in the function contains_point in matplotlib.path is defined inconsistently. This function checks if a specified point is inside or outside of a closed path. The radius parameter is used to make the path a little bit smaller/larger (dependent on the sign of radius). In this way, points can be taken into/out of account, which are close to the path. The problem is, that the sign of radius depends on the orientation of the path (clockwise or counterclockwise). The inconsistency (in my opinion) is there, because the orientation of path is ignored when checking if a

I need to run a jquery only if the bold element contains particular text. What am I doing wrong? <script> if ($('b:contains('Choose a sub category:')')) { $("td.colors_backgroundneutral").css("background-color","transparent"); $("td.colors_backgroundneutral").children(':first-child').attr("cellpadding","0"); }; </script> Besides using single quotes inside single quotes, which breaks the string, you're using a jQuery selector inside an if statement. This selector only filters your b tags to those which contain "Choose a sub category"; and then returns a list of those elements. It does not

I have a situation where I need to try and filter out fake SSN numbers. From what I've seen so far if they are fake they're all the same number or 123456789. I can filter for the last one, but is there an easy way to determine if all the characters are the same? return (ssn. Distinct() .Count() == 1) This method should do the trick: public static bool AreAllCharactersSame(string s) { return s.Length == 0 || s.All(ch => ch == s[0]); } Explanation: if a string's length is 0, then of course all characters are the same. Otherwise, a string's characters are all the same if they are all equal to the
