For query 0, place an obstacle at x = 2. A block of size at most 2 can be placed before x = 3.
There exists an infinite number line, with its origin at 0 and extending towards the positive x-axis.
\n\nYou are given a 2D array queries, which contains two types of queries:
queries[i] = [1, x]. Build an obstacle at distance x from the origin. It is guaranteed that there is no obstacle at distance x when the query is asked.queries[i] = [2, x, sz]. Check if it is possible to place a block of size sz anywhere in the range [0, x] on the line, such that the block entirely lies in the range [0, x]. A block cannot be placed if it intersects with any obstacle, but it may touch it. Note that you do not actually place the block. Queries are separate.Return a boolean array results, where results[i] is true if you can place the block specified in the ith query of type 2, and false otherwise.
\n
Example 1:
\n\nInput: queries = [[1,2],[2,3,3],[2,3,1],[2,2,2]]
\n\nOutput: [false,true,true]
\n\nExplanation:
\n\n
For query 0, place an obstacle at x = 2. A block of size at most 2 can be placed before x = 3.
Example 2:
\n\nInput: queries = [[1,7],[2,7,6],[1,2],[2,7,5],[2,7,6]]
\n\nOutput: [true,true,false]
\n\nExplanation:
\n\n![\"\"](\"https://assets.leetcode.com/uploads/2024/04/22/example1block.png\")
x = 7 for query 0. A block of size at most 7 can be placed before x = 7.x = 2 for query 2. Now, a block of size at most 5 can be placed before x = 7, and a block of size at most 2 before x = 2.\n
Constraints:
\n\n1 <= queries.length <= 15 * 1042 <= queries[i].length <= 31 <= queries[i][0] <= 21 <= x, sz <= min(5 * 104, 3 * queries.length)x when the query is asked.有一条无限长的数轴，原点在 0 处，沿着 x 轴 正 方向无限延伸。
\n\n给你一个二维数组 queries ，它包含两种操作：
queries[i] = [1, x] 。在距离原点 x 处建一个障碍物。数据保证当操作执行的时候，位置 x 处 没有 任何障碍物。queries[i] = [2, x, sz] 。判断在数轴范围 [0, x] 内是否可以放置一个长度为 sz 的物块，这个物块需要 完全 放置在范围 [0, x] 内。如果物块与任何障碍物有重合，那么这个物块 不能 被放置，但物块可以与障碍物刚好接触。注意，你只是进行查询，并 不是 真的放置这个物块。每个查询都是相互独立的。请你返回一个 boolean 数组results ，如果第 i 个操作类型 2 的操作你可以放置物块，那么 results[i] 为 true ，否则为 false 。
\n\n
示例 1：
\n\n输入：queries = [[1,2],[2,3,3],[2,3,1],[2,2,2]]
\n\n输出：[false,true,true]
\n\n解释：
\n\n
查询 0 ，在 x = 2 处放置一个障碍物。在 x = 3 之前任何大小不超过 2 的物块都可以被放置。
示例 2：
\n\n输入：queries = [[1,7],[2,7,6],[1,2],[2,7,5],[2,7,6]]
\n\n输出：[true,true,false]
\n\n解释：
\n\n
x = 7 处放置一个障碍物。在 x = 7 之前任何大小不超过 7 的物块都可以被放置。x = 2 处放置一个障碍物。现在，在 x = 7 之前任何大小不超过 5 的物块可以被放置，x = 2 之前任何大小不超过 2 的物块可以被放置。\n\n
提示：
\n\n1 <= queries.length <= 15 * 1042 <= queries[i].length <= 31 <= queries[i][0] <= 21 <= x, sz <= min(5 * 104, 3 * queries.length)x 处不会有障碍物。d[x] be the distance of the next obstacle after x.",
"For each query of type 2, we just need to check if max(d[0], d[1], d[2], …d[x - sz]) > sz.",
"Use segment tree to maintain d[x]."
