Permuting Two Arrays

    Kotlin one-line answer:

    fun twoArrays(k: Int, A: Array<Int>, B: Array<Int>): String {
    return if ((A.sum() + B.sum())/A.size >= k && A.min()!!+B.max()!! >= k && A.max()!!+B.min()!! >=k) "YES" else "NO"
}

    Java 8:

    public static String twoArrays(int k, List<Integer> A, List<Integer> B) {
    return (((A.stream()
  .reduce(0, Integer::sum)) + (B.stream()
  .reduce(0, Integer::sum)))/A.size() >= k && Collections.min(A) + Collections.max(B) >=k && Collections.max(A) + Collections.min(B) >=k) ? "YES" : "NO";
}
