Regex for certain words causes Spaces












2















For instance i'm trying to search this string



"this is a search LLC which can end up having spaces"



using the below regex, it's working fine but when I match and then remove it's causes a bunch of white spaces, so I want to limit the number the white space to just 1, how could I go about adding that?



(?i)(?<=|^)LLC|end|having(?=|$)



this is a search LLC which can end up having spaces



this is a search which can up spaces



public static String removeValuesByRegex(String input, Pattern pattern, String replaceWith){

    String result;



    Matcher matcher = pattern.matcher(input);



    return result = matcher.replaceAll(replaceWith).trim();

}


Then in my test class im doing



String keywords = 'LLC|end|Having';

Pattern pattern = Pattern.compile('(?i)(?<= |^)'|' + keyWords + ''|(?= |$)');



String stringResult = UtilString.removeValuesByRegex('This is a LLC and General Partnership Test ', pattern, '');

          If you want to remove duplicate spacing, I recommend you call normalizeSpace on the output:



          String result = MyClass.myMethod(input, pattern, '').normalizeSpace();


          Note from the documentation:




          normalizeSpace()

          Returns the current String with leading, trailing, and repeating white space characters removed.

          Is this a new Fibonacci Identity?

          Image
          6 1 $begingroup$ I have found the following Fibonacci Identity (and proved it). If $F_n$ denotes the nth Fibonacci Number, we have the following identity begin{equation} F_{n-r+h}F_{n+k+g+1} - F_{n-r+g}F_{n+k+h+1} = (-1)^{n+r+h+1} F_{g-h}F_{k+r+1} end{equation} where $F_1 = F_2 = 1$ , $r leq n$ , $h leq g$ , and $n, g, k in mathbb{N}$ . It is not too hard to show that this identity subsumes Cassini's Identity, Catalan's Identity, Vajda's Idenity, and d'Ocagne's identity to name a few. I have done a pretty thorough literature review, and I have not found anything like this, but I am still wondering if anyone has seen this identity before? I found this by accident after noticing some patterns in some analysis work I was doing, so if this is already known I would be curious to see w...
