Question

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String text = scanner.nextLine();
char[] arr = text.toCharArray();
char[] res = new char [arr.length];
//your code goes here
int length = arr.length;
for (int i = 0; i < arr.length; i++){
for (char b: arr){
res[i] = b;
}
}System.out.println (res);
}
}

Answer 1

Remove inner loop ;
// for ( chat b : arr) , no need

and then insert in reverse arr.length -1 to 0; not from 0 to arr.length

your loop mentaining only last values in each index. oh. you need to give a one more try.. you can reply again with your update, if you have any errors again...Dennis Besic

Answer 2

You can link your code like this:
Go to Code section, click +, select the programming language, insert your code, save.
Come back to this thread, click +, Insert Code, sort for My Code Bits, select your code.

Answer 3

Consider the following:
i = 0 and the word is "hello".
Then the for each loop does this
res[0] = 'h'
res[0] = 'e'
res[0] = 'l'
res[0] = 'l'
res[0] = 'o'
