-/**
- * Algorithm: Binary Search
- * Category: Searching
- *
- * Description:
- * An efficient search algorithm that finds the position of a target value
- * within a sorted array. Binary search compares the target value to the middle
- * element of the array. If they are not equal, the half in which the target cannot
- * lie is eliminated and the search continues on the remaining half, again taking
- * the middle element to compare to the target value, and repeating until the target
- * value is found or the array is exhausted.
- *
- * Time Complexity: O(log n)
- * Space Complexity: O(1)
- *
- * Parameters:
- * - arr: A sorted array of elements
- * - target: The value to search for in the array
- * - left: The starting index of the search range (optional)
- * - right: The ending index of the search range (optional)
- *
- * Returns:
- * - The index of the target if found, otherwise -1
- *
- * Example Usage:
- * vector<int> nums = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
- * int target = 7;
- * int result = binarySearch(nums, target);  // Returns 6
- *
- * Variants:
- * - Lower bound: Find the first element >= target
- * - Upper bound: Find the first element > target
- * - Closest element: Find the element closest to target
- *
- * References:
- * - Introduction to Algorithms (CLRS), Chapter 2.3

+ * 相关知识：
+ * 1. 极坐标与直角坐标转换
+ *   - 使用atan2(y,x)计算点(x,y)与x轴的夹角
+ *   - 使用sqrt(x^2 + y^2)计算点到原点的距离
+ *
+ * 2. 三角函数
+ *   - asin(x)计算x的反正弦值
+ *   - 用于计算地雷覆盖的扇形角度
+ *
+ * 3. 区间合并
+ *   - 将重叠的区间合并为更大的区间
+ *   - 使用sort对区间按起始角度排序
+ *   - 遍历区间，合并重叠部分
+ *
+ * 4. 浮点数输出控制
+ *   - 使用fixed和setprecision控制输出精度
