Please check.

import java.util.*;
public class Main {

public static int findLenRec(String[] s, int i, String res)  {

    if(i == s.length) {
        int[] freq = new int[26];

        for(int j = 0; j < res.length(); j++) {
            if(freq[res.charAt(j) - 'a'] == 1) {
                return 0;
            } 

            freq[res.charAt(j) - 'a']++;
        }
        return res.length();
    }

    int a = Integer.MIN_VALUE;
    int b = Integer.MIN_VALUE;

    if(res.length() + s[i].length() <= 26) {
        a = findLenRec(s, i + 1, res + s[i]);
    }

    b = findLenRec(s, i + 1, res);

    return Math.max(a, b);


}


public static void main (String args[]) {
    Scanner scan = new Scanner(System.in);

    int n = scan.nextInt();

    String[] s = new String[n];

    for(int i=0;i<n;i++) {
        s[i] = scan.nextLine();
    }

    System.out.println(findLenRec(s, 0, ""));


}

}
