A Range Module is a module that tracks ranges of numbers. Design a data structure to track the ranges represented as half-open intervals and query about them.

\n\n

A half-open interval [left, right) denotes all the real numbers x where left <= x < right.

\n\n

Implement the RangeModule class:

\n\n\n\n

 

\n

Example 1:

\n\n
\nInput\n["RangeModule", "addRange", "removeRange", "queryRange", "queryRange", "queryRange"]\n[[], [10, 20], [14, 16], [10, 14], [13, 15], [16, 17]]\nOutput\n[null, null, null, true, false, true]\n\nExplanation\nRangeModule rangeModule = new RangeModule();\nrangeModule.addRange(10, 20);\nrangeModule.removeRange(14, 16);\nrangeModule.queryRange(10, 14); // return True,(Every number in [10, 14) is being tracked)\nrangeModule.queryRange(13, 15); // return False,(Numbers like 14, 14.03, 14.17 in [13, 15) are not being tracked)\nrangeModule.queryRange(16, 17); // return True, (The number 16 in [16, 17) is still being tracked, despite the remove operation)\n

Range模块是跟踪数字范围的模块。设计一个数据结构来跟踪表示为 半开区间 的范围并查询它们。

\n\n

半开区间 [left, right) 表示所有 left <= x < right 的实数 x 。

\n\n

实现 RangeModule 类:

\n\n\n\n

 

\n\n

示例 1：

\n\n
\n输入\n[\"RangeModule\", \"addRange\", \"removeRange\", \"queryRange\", \"queryRange\", \"queryRange\"]\n[[], [10, 20], [14, 16], [10, 14], [13, 15], [16, 17]]\n输出\n[null, null, null, true, false, true]\n\n解释\nRangeModule rangeModule = new RangeModule();\nrangeModule.addRange(10, 20);\nrangeModule.removeRange(14, 16);\nrangeModule.queryRange(10, 14); 返回 true （区间 [10, 14) 中的每个数都正在被跟踪）\nrangeModule.queryRange(13, 15); 返回 false（未跟踪区间 [13, 15) 中像 14, 14.03, 14.17 这样的数字）\nrangeModule.queryRange(16, 17); 返回 true （尽管执行了删除操作，区间 [16, 17) 中的数字 16 仍然会被跟踪）\n
