Segment Tree Approach

  1. Define a Node class representing a segment tree node with properties for the interval boundaries, a boolean indicating if the interval is tracked, and pointers to left and right child nodes.
  2. Implement the addRange function to update the tree by setting the tracked property to true for the given interval.
  3. Implement the queryRange function to check if the entire interval is tracked by traversing the tree.
  4. Implement the removeRange function to update the tree by setting the tracked property to false for the given interval.
  5. Use lazy propagation to mark child nodes as needed without immediate updates to optimize the tree modification operations.
