You are given a 2D integer array intervals, where intervals[i] = [lefti, righti] describes the ith interval starting at lefti and ending at righti (inclusive). The size of an interval is defined as the number of integers it contains, or more formally righti - lefti + 1.
You are also given an integer array queries. The answer to the jth query is the size of the smallest interval i such that lefti <= queries[j] <= righti. If no such interval exists, the answer is -1.
Return an array containing the answers to the queries.

Example 1:
\n\n\nInput: intervals = [[1,4],[2,4],[3,6],[4,4]], queries = [2,3,4,5]\nOutput: [3,3,1,4]\nExplanation: The queries are processed as follows:\n- Query = 2: The interval [2,4] is the smallest interval containing 2. The answer is 4 - 2 + 1 = 3.\n- Query = 3: The interval [2,4] is the smallest interval containing 3. The answer is 4 - 2 + 1 = 3.\n- Query = 4: The interval [4,4] is the smallest interval containing 4. The answer is 4 - 4 + 1 = 1.\n- Query = 5: The interval [3,6] is the smallest interval containing 5. The answer is 6 - 3 + 1 = 4.\n\n\n
Example 2:
\n\n\nInput: intervals = [[2,3],[2,5],[1,8],[20,25]], queries = [2,19,5,22]\nOutput: [2,-1,4,6]\nExplanation: The queries are processed as follows:\n- Query = 2: The interval [2,3] is the smallest interval containing 2. The answer is 3 - 2 + 1 = 2.\n- Query = 19: None of the intervals contain 19. The answer is -1.\n- Query = 5: The interval [2,5] is the smallest interval containing 5. The answer is 5 - 2 + 1 = 4.\n- Query = 22: The interval [20,25] is the smallest interval containing 22. The answer is 25 - 20 + 1 = 6.\n\n\n

Constraints:
\n\n1 <= intervals.length <= 1051 <= queries.length <= 105intervals[i].length == 21 <= lefti <= righti <= 1071 <= queries[j] <= 107给你一个二维整数数组 intervals ，其中 intervals[i] = [lefti, righti] 表示第 i 个区间开始于 lefti 、结束于 righti（包含两侧取值，闭区间）。区间的 长度 定义为区间中包含的整数数目，更正式地表达是 righti - lefti + 1 。
再给你一个整数数组 queries 。第 j 个查询的答案是满足 lefti <= queries[j] <= righti 的 长度最小区间 i 的长度 。如果不存在这样的区间，那么答案是 -1 。
以数组形式返回对应查询的所有答案。

示例 1：
\n\n\n输入：intervals = [[1,4],[2,4],[3,6],[4,4]], queries = [2,3,4,5]\n输出：[3,3,1,4]\n解释：查询处理如下：\n- Query = 2 ：区间 [2,4] 是包含 2 的最小区间，答案为 4 - 2 + 1 = 3 。\n- Query = 3 ：区间 [2,4] 是包含 3 的最小区间，答案为 4 - 2 + 1 = 3 。\n- Query = 4 ：区间 [4,4] 是包含 4 的最小区间，答案为 4 - 4 + 1 = 1 。\n- Query = 5 ：区间 [3,6] 是包含 5 的最小区间，答案为 6 - 3 + 1 = 4 。\n\n\n
示例 2：
\n\n\n输入：intervals = [[2,3],[2,5],[1,8],[20,25]], queries = [2,19,5,22]\n输出：[2,-1,4,6]\n解释：查询处理如下：\n- Query = 2 ：区间 [2,3] 是包含 2 的最小区间，答案为 3 - 2 + 1 = 2 。\n- Query = 19：不存在包含 19 的区间，答案为 -1 。\n- Query = 5 ：区间 [2,5] 是包含 5 的最小区间，答案为 5 - 2 + 1 = 4 。\n- Query = 22：区间 [20,25] 是包含 22 的最小区间，答案为 25 - 20 + 1 = 6 。\n\n\n
