Example: Input: Geeksforgeeks Output: Geksforg Input: Geeksforgeeks is a great site for computer science Output: Geksforg Iaticmpun To achieve this, we have the following approaches: Approach 1: This is a naive approach to find the unique characters from a string. In this approach, we create a variable name uniq and we are iterating over the string using the for loop and at every iteration, we are checking if the uniq contains the character. Javascript
Output: "Geksforg" "Geksforg Iaticmpun" Approach 2: In this method, we use the set data structure. The set data structure contains only unique values, and we take the advantage of it. So to extract the unique values from string using Set we follow the steps below.
Javascript
Output: "Geksforg" "Geksforg Iaticmpun" Approach 3: In this approach first, we convert the string into an array using the spread operator e.g. […str] and then we apply the reduce method on that array. Javascript
Output: "Geksforg" "Geksforg Iaticmpun" Approach-4: In this approach we will use a for-loop in order to iterate over the complete string and then by using the indexOf() method we will check the index of each and every character (using charAt() method) of the string which is either repeated or not repeated and then in an empty string (which we will declare initially) we will store all the unique characters. Javascript
Output: Geksforg What are the special characters in JavaScript?Special characters. What is unique string?A Java String contains an immutable sequence of Unicode characters. Unlike C/C++, where string is simply an array of char , A Java String is an object of the class java. lang. String .
