Kotlin | Reversing each word in string: Here, we are going to learn how to reverse each words in the given string in Kotlin programming language?
Submitted by IncludeHelp, on April 29, 2020

Given a string, we have to reverse its each word.

Example:

    Input:
    string = "Hello world"

    Output:
    "olleH dlrow"

Program to reverse each word in Kotlin

At first, we are reading a string, then splitting and converting the string to a string list, then extracting each word, reversing the words, and finally creating the string with reverse words.

package com.includehelp.basic

import java.util.*

//Method to reverse each word in provided April20.string
fun reverseWord(inputString: String): String {
    //split April20.string by space
    val strList = inputString.split(" ")  // Spilt String by Space
    val sb = StringBuilder()

    //iterate April20.string List
    for (items in strList) {
        if (items != "") {
            //reverse List item and reverse them
            val rev = StringBuilder(items).reverse().toString()

            //append reverse April20.string into String Builder
            sb.append("$rev ")
        }
    }

    //return final reverse April20.string
    return sb.toString()
}

//Main Function, entry Point of Program
fun main(args: Array<String>) {

    //Input Stream
    val sc = Scanner(System.`in`)

    //input April20.string value
    println("Input String : ")
    val str: String = sc.nextLine()

    println("Input String : $str")

    //Call function for reverse words in April20.string and print them
    println("String with Reverse Word : " + reverseWord(str))
}

Output

Run 1:
Input String :
Hello include help
Input String : Hello include help
String with Reverse Word : olleH edulcni pleh
---
Input String :
Hello I am in Delhi, How are you
Input String : Hello I am in Delhi, How are you
String with Reverse Word : olleH I ma ni ,ihleD woH era uoy
