For my program I want to reverse letters in a line of text. However I don't want to reverse the order of the words in the sentence. For example when I input: "This is a string"

I get: gnirts a si siht

But I want: siht si a gnirts

public static String reverseWordCharacters(String text1) {        String reverse = "";        int length = text1.length();        for (int i = length - 1; i >= 0; i--) {            reverse = reverse + text1.charAt(i);            System.out.println();        }        return reverse;    }}

I need a little help. I found a question like "Write a Java program that will reverse each word of user given string without altering their position and using any built in function."

I solved a code for reversing the whole sentence, but I don't know how to solve this one. Please help me...

import java.io.*;class test25 {     public static void main(String args[]) throws IOException {         BufferedReader br = new BufferedReader(new InputStreamReader(System.in));        System.out.print("Enter string: ");        String s = br.readLine();        String reverse = "";        int length = s.length();        for (int i = length - 1; i >= 0; i--)            reverse = reverse + s.charAt(i);        System.out.println("Result:" + reverse);     } }

How do you reverse a string in place (or in-place) in JavaScript when passed to a function with a return statement? All without using the built-in functions? .reverse(), .charAt(), etc.

Now I want to implement a function to "reverse" a given string. My idea was not to swap, rather I thought of declaring a new array in the implemented function to absorb the new string in its reversed state.Here is the code:

#include <stdio.h>#include <stdlib.h>void reverseString( char string[  ], int size );int main(){    char string[ 14 ] = "reverse me";    printf( "The string is: %s\n", string );    reverseString( string, 14 );    return 0;}void reverseString( char string[  ], int size ){    int i, j;    char newString[ size ];    for( ( i = ( size ) ) & ( j = 0 ); ( i >= 0 ) && ( j < ( size ) ); i-- & j ++ )    {        newString[ j ] = string[ i ];    }    printf( "\nThe string reversed: %s\n", newString );}

could anybody please help me to get the idea of reversing strings? Was I approaching the idea when looking at my code or what ?!

I need a code to reverse order only the alphabets, without reversing the numbers.For Ex. Suppose I have :3 D F 4 B 5 H 6 K (in a string or array) I should produce output:3 K H 4 B 5 F 6 D
