You can use regex to selecting target part of string and run it in preg_replace(). $url = “http://aaa-aaaa.com/bbbb-bbbbbbbbbb-2/it/clients/”; echo preg_replace(“@(.*)\w{2}/([^/]+/)$@”, “$1$2”, $url); See result of code in demo solved Remove only 3 characters after a specific string
You could use Regex.Replace(String, String, Int32) for this, execute until all of the intended replacements from arr are replaced. var text = File.ReadAllText(“file.txt”); var arr = new[] { “A”, “B”, “A” }; var regex = new Regex(“b”); for(int i = 0; i < arr.Count; i++) text = regex.Replace(text, arr[i].ToString(), 1); Tip: Never answer when tired… … Read more
You are comparing all the characters of the String against all the characters of the same String, so of course you find a match and return “yes”. You only need a single loop. All you need is : e = 0; for ( int i = 0 ; i <t ; i++) { f = … Read more
That isn’t a concatenation: you’re not appending this to anything else. It’s only a value substitution. Thus, you should (1) use the variable name, rather than a string; (2) leave out the concatenation attempt. “device-id”: d1, This should substitute the desired value of varibale d1. solved Python String concatenation with in double quotes [closed]

Not tested with data set but checking to the source codes of compareTo and matches it seems compareTo would be faster as matches then again calls Pattern.matches and includes other function calls as well (since matches takes regex as input – regex compilation puts extra overhead. Though since matches accepts regex as well it has … Read more
Use the comparator, and then, the Float Comparator: Arrays.sort(strengths, new Comparator<String>() { @Override public int compare(String o1, String o2) { return Float.compare(Float.valueOf(o1.split(” “)[0]), Float.valueOf(o2.split(” “)[0])); } }); 0 solved Sort string array by first part of each element in java

Javascript – What is the best way to remove alternate repeating character in a given string with time complexity O(n) and Space Complexity was O(1)? solved Javascript – What is the best way to remove alternate repeating character in a given string with time complexity O(n) and Space Complexity was O(1)?
You can split the string on / and then use int.TryParse on the first element of array to see if it is an integer like: string str = “1234/xxxxx”; string[] array = str.Split(new []{“https://stackoverflow.com/”}, StringSplitOptions.RemoveEmptyEntries); int number = 0; if (str.Length == 2 && int.TryParse(array[0], out number)) { //parsing successful. } else { //invalid number … Read more
You can iterate through the String and look for a character you seek. Just use a for loop like this: String test = “I want to test something”; for(int i=0;i<test.length;i++) { char t = test.charAt(i); // do something with char } https://docs.oracle.com/javase/7/docs/api/java/lang/String.html#charAt%28int%29 3 solved How to get a character index in a string [closed]
