Finalizing the multigram logic

Okay, after breaking down the string "xyyyxyyyx," I see it can be partitioned into substrings of size 3: "xyy", "yxy", and "yyx", which are all anagrams of each other, making 3 the valid substring length. The key idea is to find the smallest substring length (L) that can divide the original string into substrings that are anagrams of each other. If no such length exists, the answer is -1. I'll stick with this approach for the code.

Constructing the shortest anagram code

I’m thinking through the algorithm to solve the problem. First off, I’ll loop through substring lengths LL from 1 to n/2n/2. If the string length is divisible by LL, I’ll check if all substrings of that length have matching character frequencies. If they do, I’ll return the first substring. Otherwise, after checking all possibilities, I’ll return -1. The solution seems feasible with a complexity of O(N2)O(N^2), which should work for N<200N < 200. Now, I’ll write the code for this.

Here’s the completed solution in the exact skeleton shown in the screenshots:

java
import java.util.*;

public class TestClass
{
    //  str is the input string
    public static String shortestAnagram(String str)
    {
        int n = str.length();

        // try every possible block length (must divide n and give ≥ 2 blocks)
        for (int len = 1; len <= n / 2; len++)
        {
            if (n % len != 0) continue;          // block size must divide n

            // frequency count for the first block
            int[] base = new int[26];
            for (int i = 0; i < len; i++)
                base[str.charAt(i) - 'a']++;

            boolean ok = true;

            // compare every subsequent block’s frequency with the first
            for (int start = len; start < n; start += len)
            {
                int[] cur = new int[26];
                for (int i = start; i < start + len; i++)
                    cur[str.charAt(i) - 'a']++;

                if (!Arrays.equals(base, cur))
                {
                    ok = false;
                    break;
                }
            }

            if (ok)                 // found the minimal-length block
                return str.substring(0, len);
        }
        return "-1";                // not a multigram
    }

    public static void main(String[] arg)
    {
        Scanner sc = new Scanner(System.in);
        String str = sc.nextLine().trim();
        System.out.println(shortestAnagram(str));
        sc.close();
    }
}

How it works

  1. Iterate over every block length that divides the string (up to n/2, so at least two blocks will exist).
  2. Record character frequencies (base) for the first block.
  3. Slide through the rest of the string in blocks of that length, ensuring each has identical frequencies (Arrays.equals).
  4. The first length that satisfies the check is the shortest anagram; return its substring.
  5. If no length works, the word is not a multigram, so print -1.
