843. Guess the Word
Explanation:
- We can solve this problem using the minimax algorithm combined with a heuristic function to minimize the number of incorrect guesses.
- The basic idea is to select a word from the list of words and use the feedback from the Master.guess() method to eliminate other words that do not match the feedback.
- We keep track of the count of exact matches between the guessed word and the secret word to guide our next guess.
- By selecting the next guess intelligently based on the feedback received, we can minimize the number of guesses required to find the secret word. :
import java.util.*;
class Solution {
public void findSecretWord(String[] wordlist, Master master) {
List<String> words = new ArrayList<>(Arrays.asList(wordlist));
for (int i = 0; i < 10; i++) {
String guess = getBestGuess(words);
int match = master.guess(guess);
if (match == 6) {
return;
}
words = filterWords(words, guess, match);
}
}
private String getBestGuess(List<String> words) {
return words.get((int) (Math.random() * words.size()));
}
private List<String> filterWords(List<String> words, String guess, int match) {
List<String> filtered = new ArrayList<>();
for (String word : words) {
if (countMatches(word, guess) == match) {
filtered.add(word);
}
}
return filtered;
}
private int countMatches(String word1, String word2) {
int count = 0;
for (int i = 0; i < word1.length(); i++) {
if (word1.charAt(i) == word2.charAt(i)) {
count++;
}
}
return count;
}
