Reverse of a array

Question

Pls find the error

Answer 1

When iterating backwards the first index should be arr.length -1, not arr.length.

Answer 2

Use i>=0 rather than i>0 when iterating backwards.

Answer 3

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[] c;
//your code goes here
for(int i=arr.length;i>0;i--)
c[]=arr[i];
for(int i=0;i<arr.length;i++)
System.out.print(c[]);
}
}
