-Implement the `remove(u)` method, that removes the node `u` from a
-`MeldableHeap`. This method should run in `O(log n)` expected time.
-
-```java
-class MeldableHeap {
-  Node<T> merge(Node<T> h1, Node<T> h2) {
-    if (h1 == nil) return h2;
-    if (h2 == nil) return h1;
-    if (compare(h2.x, h1.x) < 0) return merge(h2, h1);
-
-    if (rand.nextBoolean()) {
-      h1.left = merge(h1.left, h2);
-      h1.left.parent = h1;
-    } else {
-      h1.right = merge(h1.right, h2);
-      h1.right.parent = h1;
-    }
-    return h1;
-  }
-
-  boolean add(T x) {
-    Node<T> u = newNode();
-    u.x = x;
-    r = merge(u, r);
-    r.parent = nil;
-    n++;
-    return true;
-  }
-
-  T remove() {
-    T x = r.x;
-    r = merge(r.left, r.right);
-    if (r != nil) r.parent = nil;
-    n--;
-    return x;
-  }
