I have the following regex:
/\.([s]?[ac]ss)$/. The problem is, it matches
.ass. How would I make it not match

I have an array of 5 numbers, I'd like to match as long as there are three of the same number and two of the same different number in the array, placement does not matter. Number sequences can be any random string of 5 numbers between 1 - 5.
Examples of matches would be:
*basically any grouping of 2 and 3 of the same numbers needs to match.

A simple solution would be to convert all characters to lowercase, replace any character that isn't a-z, 0-9, or a space with a space character, and then replace multiple space characters with a single space character.
Expected output: "TenancyAccountAccountPublicIdWorkspaceWorkspacePublicIdRemove-userUserPublicId"
- replace any character with zero or more underscore to the non-underscored uppercase
x | __*x => X
- If exists remove last _
This is what is tried so far, looking for better alternatives, if any:...

Java 11 added some new methods to the
Pattern class (a compiled version of a regular expression), including:
I am trying to understand the difference between the two and when I would want to use one over the other?...
ANSWERAnswered 2021-Nov-16 at 14:57
Pattern.asPredicatewill return true if any part of the input string matches the Regular expression. You should use this method if you're testing some larger body of text for a certain pattern. For example, to test whether a comment from a user contains a hyperlink.
Pattern.asMatchPredicatewill return true if the entire input string matches the Regular expression. You should use this method if you're testing the entire input for a certain pattern. For example, to validate the phone number of a user in their profile.
Pattern.asPredicate internally uses
Pattern.asMatchPrediate internally uses
Matcher.matches(). So the difference between the two boils down to the difference between these two methods from the
Below are some examples to showcase the difference. You can copy & paste below code in an online Java sandbox like https://www.compilejava.net/ to play around with it yourself.
I am trying to replace a single occurrence of a character '1' in a String with a different character.

I'm attempting to solve a very simple problem - find strings in an array which only contain certain letters. However, I've run up against something in the behavior of regular expressions and/or

I have a Json file having multiple comments and I want to replace a value in it.
I tried the below and it gives me a json file without comments. But I don't understand how to change the value and save it back with comments. Is this even possible because we are replacing all the comments with empty lines?...

The header question may not be easy to understand. Hope you can understand my detailed info below.
I have sentence data below, that has some tags, represented by
ANSWERAnswered 2021-Oct-04 at 08:47
Here is a solution that assumes that there are no nested tags, that all tags open and close in the part. Also, this assumes that all characters from the sentence are in
parts. For this last assumption, I had to add the
. after it has to be in the second expected part. I also had to remove newline characters from the sentence but I think it was because of the copy/paste.
This solution will loop through all characters and store two parallel buffers : one with the tags, one without. We will use the second one to compare with the parts, and use the first one to generate the output.

You can use GrepBugs like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
