        Indexing requires traversing the tree from a leaf node to the root. The
        parent of each node is easily computable at ``(pos - 1) // 2``.
        Left-child nodes are always at odd indices and right-child nodes are
        always at even indices.
        When traversing up from a right-child node, increment the total by the
        left-child node.
        The final index is the sum from traversal and the index in the sublist.
        For example, using the index from ``SortedList._build_index``::
            _index = 14 5 9 3 2 4 5

        like so:
        1. Starting at the leaf node: offset + alpha = 3 + 2 = 5. We identify
           the node as a left-child node. At such nodes, we simply traverse to
           the parent.
        2. At node 9, position 2, we recognize the node as a right-child node
           and accumulate the left-child in our total. Total is now 5 and we
           traverse to the parent at position 0.
        3. Iteration ends at the root.
        The index is then the sum of the total and sublist index: 5 + 3 = 8.

        that can be used to access the corresponding lists position.
        Many queries require the index be built. Details of the index are
        described in ``SortedList._build_index``.
        Indexing requires traversing the tree to a leaf node. Each node has two
        children which are easily computable. Given an index, pos, the
        left-child is at ``pos * 2 + 1`` and the right-child is at ``pos * 2 +
        2``.
        When the index is less than the left-child, traversal moves to the
        left sub-tree. Otherwise, the index is decremented by the left-child
        and traversal moves to the right sub-tree.
        At a child node, the indexing pair is computed from the relative
        position of the child node as compared with the offset and the remaining
        index.
        For example, using the index from ``SortedList._build_index``::
            _index = 14 5 9 3 2 4 5
            _offset = 3
        Tree::
                 14
              5      9
            3   2  4   5
        Indexing position 8 involves iterating like so:
        1. Starting at the root, position 0, 8 is compared with the left-child
           node (5) which it is greater than. When greater the index is
           decremented and the position is updated to the right child node.
        2. At node 9 with index 3, we again compare the index to the left-child
           node with value 4. Because the index is the less than the left-child
           node, we simply traverse to the left.
        3. At node 4 with index 3, we recognize that we are at a leaf node and
           stop iterating.
        4. To compute the sublist index, we subtract the offset from the index
           of the leaf node: 5 - 3 = 2. To compute the index in the sublist, we
           simply use the index remaining from iteration. In this case, 3.
        The final index pair from our example is (2, 3) which corresponds to
        index 8 in the sorted list.

            0: [1, 2, 3]
            1: [4, 5]
            2: [6, 7, 8, 9]
            3: [10, 11, 12, 13, 14]
        The first transformation maps the sub-lists by their length. The
        first row of the index is the length of the sub-lists::
            0: [3, 2, 4, 5]
        Each row after that is the sum of consecutive pairs of the previous
        row::
            1: [5, 9]
            2: [14]
        Finally, the index is built by concatenating these lists together::

        An offset storing the start of the first row is also stored::

        When built, the index can be used for efficient indexing into the list.

        Indexing requires traversing the tree from a leaf node to the root. The
        parent of each node is easily computable at ``(pos - 1) // 2``.
        Left-child nodes are always at odd indices and right-child nodes are
        always at even indices.
        When traversing up from a right-child node, increment the total by the
        left-child node.
        The final index is the sum from traversal and the index in the sublist.
        For example, using the index from ``SortedList._build_index``::

        like so:
        1. Starting at the leaf node: offset + alpha = 3 + 2 = 5. We identify
           the node as a left-child node. At such nodes, we simply traverse to
           the parent.
        2. At node 9, position 2, we recognize the node as a right-child node
           and accumulate the left-child in our total. Total is now 5 and we
           traverse to the parent at position 0.
        3. Iteration ends at the root.

        that can be used to access the corresponding lists position.
        Many queries require the index be built. Details of the index are
        described in ``SortedList._build_index``.
        Indexing requires traversing the tree to a leaf node. Each node has two
        children which are easily computable. Given an index, pos, the
        left-child is at ``pos * 2 + 1`` and the right-child is at ``pos * 2 +
        2``.
        When the index is less than the left-child, traversal moves to the
        left sub-tree. Otherwise, the index is decremented by the left-child
        and traversal moves to the right sub-tree.
        At a child node, the indexing pair is computed from the relative
        position of the child node as compared with the offset and the remaining
        index.
        For example, using the index from ``SortedList._build_index``::
            _index = 14 5 9 3 2 4 5
            _offset = 3
        Tree::

              5      9
            3   2  4   5
        Indexing position 8 involves iterating like so:
        1. Starting at the root, position 0, 8 is compared with the left-child
           node (5) which it is greater than. When greater the index is
           decremented and the position is updated to the right child node.
        2. At node 9 with index 3, we again compare the index to the left-child
           node with value 4. Because the index is the less than the left-child
           node, we simply traverse to the left.
        3. At node 4 with index 3, we recognize that we are at a leaf node and
           stop iterating.
        4. To compute the sublist index, we subtract the offset from the index
           of the leaf node: 5 - 3 = 2. To compute the index in the sublist, we
           simply use the index remaining from iteration. In this case, 3.
        The final index pair from our example is (2, 3) which corresponds to
        index 8 in the sorted list.

        Indexing requires traversing the tree from a leaf node to the root. The
        parent of each node is easily computable at ``(pos - 1) // 2``.
        Left-child nodes are always at odd indices and right-child nodes are
        always at even indices.
        When traversing up from a right-child node, increment the total by the
        left-child node.
        The final index is the sum from traversal and the index in the sublist.
        For example, using the index from ``SortedList._build_index``::
            _index = 14 5 9 3 2 4 5

        like so:
        1. Starting at the leaf node: offset + alpha = 3 + 2 = 5. We identify
           the node as a left-child node. At such nodes, we simply traverse to
           the parent.
        2. At node 9, position 2, we recognize the node as a right-child node
           and accumulate the left-child in our total. Total is now 5 and we
           traverse to the parent at position 0.
        3. Iteration ends at the root.
        The index is then the sum of the total and sublist index: 5 + 3 = 8.

        that can be used to access the corresponding lists position.
        Many queries require the index be built. Details of the index are
        described in ``SortedList._build_index``.
        Indexing requires traversing the tree to a leaf node. Each node has two
        children which are easily computable. Given an index, pos, the
        left-child is at ``pos * 2 + 1`` and the right-child is at ``pos * 2 +
        2``.
        When the index is less than the left-child, traversal moves to the
        left sub-tree. Otherwise, the index is decremented by the left-child
        and traversal moves to the right sub-tree.
        At a child node, the indexing pair is computed from the relative
        position of the child node as compared with the offset and the remaining
        index.
        For example, using the index from ``SortedList._build_index``::
            _index = 14 5 9 3 2 4 5
            _offset = 3
        Tree::
                 14
              5      9
            3   2  4   5
        Indexing position 8 involves iterating like so:
        1. Starting at the root, position 0, 8 is compared with the left-child
           node (5) which it is greater than. When greater the index is
           decremented and the position is updated to the right child node.
        2. At node 9 with index 3, we again compare the index to the left-child
           node with value 4. Because the index is the less than the left-child
           node, we simply traverse to the left.
        3. At node 4 with index 3, we recognize that we are at a leaf node and
           stop iterating.
        4. To compute the sublist index, we subtract the offset from the index
           of the leaf node: 5 - 3 = 2. To compute the index in the sublist, we
           simply use the index remaining from iteration. In this case, 3.
        The final index pair from our example is (2, 3) which corresponds to
        index 8 in the sorted list.

        described in ``SortedList._build_index``.
        Indexing requires traversing the tree from a leaf node to the root. The
        parent of each node is easily computable at ``(pos - 1) // 2``.
        Left-child nodes are always at odd indices and right-child nodes are
        always at even indices.
        When traversing up from a right-child node, increment the total by the
        left-child node.
        The final index is the sum from traversal and the index in the sublist.
        For example, using the index from ``SortedList._build_index``::
            _index = 14 5 9 3 2 4 5

        Converting an index pair (2, 3) into a single index involves iterating
        like so:
        1. Starting at the leaf node: offset + alpha = 3 + 2 = 5. We identify
           the node as a left-child node. At such nodes, we simply traverse to
           the parent.
        2. At node 9, position 2, we recognize the node as a right-child node
           and accumulate the left-child in our total. Total is now 5 and we
           traverse to the parent at position 0.
        3. Iteration ends at the root.
        The index is then the sum of the total and sublist index: 5 + 3 = 8.

        that can be used to access the corresponding lists position.
        Many queries require the index be built. Details of the index are
        described in ``SortedList._build_index``.
        Indexing requires traversing the tree to a leaf node. Each node has two
        children which are easily computable. Given an index, pos, the
        left-child is at ``pos * 2 + 1`` and the right-child is at ``pos * 2 +
        2``.
        When the index is less than the left-child, traversal moves to the
        left sub-tree. Otherwise, the index is decremented by the left-child
        and traversal moves to the right sub-tree.
        At a child node, the indexing pair is computed from the relative
        position of the child node as compared with the offset and the remaining
        index.
        For example, using the index from ``SortedList._build_index``::
            _index = 14 5 9 3 2 4 5
            _offset = 3
        Tree::
                 14
              5      9
            3   2  4   5
        Indexing position 8 involves iterating like so:
        1. Starting at the root, position 0, 8 is compared with the left-child
           node (5) which it is greater than. When greater the index is
           decremented and the position is updated to the right child node.
        2. At node 9 with index 3, we again compare the index to the left-child
           node with value 4. Because the index is the less than the left-child
           node, we simply traverse to the left.
        3. At node 4 with index 3, we recognize that we are at a leaf node and
           stop iterating.
        4. To compute the sublist index, we subtract the offset from the index
           of the leaf node: 5 - 3 = 2. To compute the index in the sublist, we
           simply use the index remaining from iteration. In this case, 3.
        The final index pair from our example is (2, 3) which corresponds to
        index 8 in the sorted list.
