My code for checking if the string is a pallindrome or not is this, but I don’t know why it is running for infinite times.
Kindly, tell me why my code is wrong…
My Code:
import java.util.*;
public class Main {
public static void main(String args[]) {
Scanner scn=new Scanner(System.in);
String str=scn.nextLine();
System.out.println(ans(str,0,str.length()-1));
}
public static boolean ans(String str,int left, int right)
{
if(left<right)
{
if(str.charAt(left)==str.charAt(right))
{
return ans(str,left++,right--);
}
else
return false;
}
else
return true;
}
}
