Given 2 strings, a and b, return a string of the form short+long+short in JAVA.. If "hi" and "hello", then "hihellohi"?

Question

Given 2 strings, a and b, return a string of the form shorterString+longerString+shorterString, with the shorter string on the outside and the longer string on the inside. The strings will not be the same length, but they may be empty (length 0). If input is "hi" and "hello", then output will be "hihellohi".

Answer 1

Try this solution :

/* package whatever; // don't place package name! */
import java.util.*;
import java.lang.*;
import java.io.*;
/* Name of the class has to be "Main" only if the class is public. */
class Ideone
{
    public static void main (String[] args) throws java.lang.Exception
    {
        // your code goes here
        Scanner scanner = new Scanner(System.in);
        String a = scanner.next();
        String b = scanner.next();
        if(a.length() > b.length())
        System.out.println(b+a+b);
        else
        System.out.println(a+b+a);
    }
}
