It returns a string after removing the first n character. Here, we are going to learn how to find first non-repeating character in a given string in Kotlin programming language? String Literals. kotlin-serialization: Any way to get character indices from a string being decoded? The result you get is the substring after the first appearance of delimiter.If the source string does not contain the delimiter, then the … Kotlin strings are also immutable in nature means we can not change elements and length of the String.
