    Java: 

    public static String twoStrings(String s1, String s2) {
  boolean[] charPresence = new boolean[26]; // a to z

  // Mark characters present in the array
  for (char c : s1.toCharArray()) {
    charPresence[c - 'a'] = true;
  }

  // Check if any character in the second string exists in the array
  for (char c : s2.toCharArray()) {
    if (charPresence[c - 'a']) {
      return "YES"; // Common character found
    }
  }

  return "NO"; // No common character found
}
