 -   线段树的每个节点代表一个区间；
 -   线段树具有唯一的根节点，代表的区间是整个统计范围，如 $[1,N]$；
 -   线段树的每个叶子节点代表一个长度为 $1$ 的元区间 $[x,x]$；
 -   对于每个内部节点 $[l,r]$，它的左儿子是 $[l,mid]$，右儿子是 $[mid+1,r]$, 其中 $mid=⌊(l+r)/2⌋$ (即向下取整)。
 
+由于题目数据范围较大，我们可以使用动态开点的线段树来实现。动态开点的线段树是指，我们只在需要的时候才开点，而不是一开始就开好所有的点。这样可以节省空间，但是需要使用**懒标记**来维护区间修改。
+
+时间复杂度方面，每次操作的时间复杂度为 $O(\log n)$。空间复杂度为 $O(m \times \log n)$。其中 $m$ 为操作次数，而 $n$ 为数据范围。

 ## Solutions
 
-Segment Tree.
+**Solution 1: Segment Tree**
+
+According to the problem description, we need to maintain a set of intervals, supporting operations of interval addition, deletion, and query. For the addition and deletion of intervals, we can use a segment tree to maintain the set of intervals.
+
+The segment tree divides the entire interval into multiple non-continuous sub-intervals, the number of which does not exceed $\log(width)$. To update the value of an element, only $\log(width)$ intervals need to be updated, and these intervals are all included in a large interval containing the element. When modifying the interval, we need to use **lazy propagation** to ensure efficiency.
+
+-   Each node of the segment tree represents an interval;
+-   The segment tree has a unique root node, representing the entire statistical range, such as $[1,N]$;
+-   Each leaf node of the segment tree represents an elementary interval of length $1$, $[x,x]$;
+-   For each internal node $[l,r]$, its left child is $[l,mid]$, and the right child is $[mid+1,r]$, where $mid=⌊(l+r)/2⌋$ (rounded down).
+
+Due to the large data range of the problem, we can implement it with a dynamically allocated segment tree. A dynamically allocated segment tree means that we only allocate nodes when needed, instead of allocating all nodes at the beginning. This can save space, but it requires **lazy propagation** to maintain interval modification.
+
+In terms of time complexity, the time complexity of each operation is $O(\log n)$. The space complexity is $O(m \times \log n)$. Here, $m$ is the number of operations, and $n$ is the data range.
