+
+
+## 题目
+
+You are given a list of gas stations on a circular route, where the amount of gas at station i is gas[i], and the cost to travel from station i to its next station (i+1) is cost[i]. You have a car with an unlimited gas tank and it costs cost[i] of gas to travel from station i to its next station (i+1). You begin the journey with an empty tank at one of the gas stations.
+
+Write a function that returns the starting gas station's index if you can travel around the circuit once in the clockwise direction, otherwise return -1. If there exists a solution, it is guaranteed to be unique.
+
+**Example 1:**
+
+```
+Input: gas = [1,2,3,4,5], cost = [3,4,5,1,2]
+Output: 3
+Explanation: Start at station 3 (index 3), you have 4 liters of gas. Now you have a total of =0+4=4 liters of gas.
+Travel to station 4. Now you have 4 - 1 + 5 = 8 liters of gas.
+Travel to station 0. Now you have 8 - 2 + 1 = 7 liters of gas.
+Travel to station 1. Now you have 7 - 3 + 2 = 6 liters of gas.
+Travel to station 2. Now you have 6 - 4 + 3 = 5 liters of gas.
+Travel to station 3 again. This time you will have consumed 5 liters of gas, which is exactly enough for you to return to station 3.
+Therefore, 3 can be the starting index.
+```
+
+**Example 2:**
+
+```
+Input: gas = [2,3,4], cost = [3,4,3]
+Output: -1
+Explanation: You cannot start at station 0 or 1 because there is not enough gas to get you to the next station.
+We start at station 2, we get 4 liters of gas. Now you have a total of =0+4=4 liters of gas.
+Travel to station 0. Now you have 4 - 3 + 2 = 3 liters of gas.
+Travel to station 1. Now you have 3 - 3 + 3 = 3 liters of gas.
+You cannot return to station 2 because it requires 4 liters of gas but you only have 3 liters in your tank.
+Therefore, no matter what, you cannot travel around the ring.
+```
+
+**Constraints:**
+
+- `gas.length == n`
+- `cost.length == n`
+- `1 <= n <= 10^5`
+- `0 <= gas[i], cost[i] <= 10^4`
+
+## 题目大意
+
+在一条环路上有 n 个加油站，其中第 i 个加油站有汽油 gas[i] 升。
+
+你有一辆油箱容量无限的的汽车，从第 i 个加油站开往第 i+1 个加油站需要消耗汽油 cost[i] 升。你从其中的一个加油站出发，开始时油箱为空。
+
+给定两个整数数组 gas 和 cost ，如果你可以按顺序绕环路行驶一周，则返回出发时加油站的编号，否则返回 -1 。如果存在解，则 保证 它是 唯一 的。
+
+## 解题思路
+
+- 初始化总油量（totalGas）和总消耗（totalCost）为0，起始点（start）为0，当前油量（currGas）为0。
+  遍历每个加油站，累加油量和消耗，计算当前油量。
+  如果当前油量小于0，说明从上一个加油站到当前加油站的油量不足以到达下一个加油站，因此将起始点设置为当前加油站的下一个位置，并将当前油量重置为0。
+  遍历结束后，如果总油量小于总消耗，说明无法完成整个旅程，返回-1；否则返回起始点。

+# [2021. Brightest Position on Street](https://leetcode.com/problems/brightest-position-on-street/)
+
+
+## 题目
+
+A perfectly straight street is represented by a number line. The street has street lamp(s) on it and is represented by a 2D integer array `lights`. Each `lights[i] = [positioni, rangei]` indicates that there is a street lamp at position `positioni` that lights up the area from `[positioni - rangei, positioni + rangei]` (**inclusive**).
+
+The **brightness** of a position `p` is defined as the number of street lamp that light up the position `p`.
+
+Given `lights`, return *the **brightest** position on the street. If there are multiple brightest positions, return the **smallest** one.*
+
+**Example 1:**
+
+![https://assets.leetcode.com/uploads/2021/09/28/image-20210928155140-1.png](https://assets.leetcode.com/uploads/2021/09/28/image-20210928155140-1.png)
+
+```
+Input: lights = [[-3,2],[1,2],[3,3]]
+Output: -1
+Explanation:
+The first street lamp lights up the area from [(-3) - 2, (-3) + 2] = [-5, -1].
+The second street lamp lights up the area from [1 - 2, 1 + 2] = [-1, 3].
+The third street lamp lights up the area from [3 - 3, 3 + 3] = [0, 6].
+
+Position -1 has a brightness of 2, illuminated by the first and second street light.
+Positions 0, 1, 2, and 3 have a brightness of 2, illuminated by the second and third street light.
+Out of all these positions, -1 is the smallest, so return it.
+
+```
+
+**Example 2:**
+
+```
+Input: lights = [[1,0],[0,1]]
+Output: 1
+Explanation:
+The first street lamp lights up the area from [1 - 0, 1 + 0] = [1, 1].
+The second street lamp lights up the area from [0 - 1, 0 + 1] = [-1, 1].
+
+Position 1 has a brightness of 2, illuminated by the first and second street light.
+Return 1 because it is the brightest position on the street.
+
+```
+
+**Example 3:**
+
+```
+Input: lights = [[1,2]]
+Output: -1
+Explanation:
+The first street lamp lights up the area from [1 - 2, 1 + 2] = [-1, 3].
+
+Positions -1, 0, 1, 2, and 3 have a brightness of 1, illuminated by the first street light.
+Out of all these positions, -1 is the smallest, so return it.
+
+```
+
+**Constraints:**
+
+- `1 <= lights.length <= 105`
+- `lights[i].length == 2`
+- `108 <= positioni <= 108`
+- `0 <= rangei <= 108`
+
+## 题目大意
+
+一条完全笔直的街道由一条数字线表示。街道上有路灯，由二维数据表示。每个 `lights[i] = [positioni, rangei]` 表示位置 `i` 处有一盏路灯，灯可以照亮从 `[positioni - rangei, positioni + rangei]` （含）的区域。 位置 `p` 的亮度定义为点亮位置 `p` 的路灯数量。 给定路灯，返回街道上最亮的位置。如果有多个最亮的位置，则返回最小的一个。
+
+## 解题思路
+
+- 先将每个路灯的起始和终点位置计算出来。这样我们得到了一堆坐标点。假设灯照亮的范围是 [A, B]，那么在坐标轴上 A 坐标点处 + 1， B + 1 坐标点处 -1 。这样处理的含义是：坐标点 A 可以被一盏灯照亮，所以它照亮次数加一，坐标点 B + 1 出了灯照亮的范围了，所以照亮次数减一。那么从坐标轴坐标开始扫一遍，每次遇到 + 1 的时候就 + 1，遇到 - 1 的地方就 - 1。如此可以算出某个坐标点处，可以被灯照亮的总次数。
+- 需要注意的点是，题目给的测试数据可能会有单点照亮的情况，即某一盏灯只照亮一个坐标点，灯照范围为 0。同一个坐标点也可能是多个灯的起点。用一个 map 去重坐标点即可。

 - 题目要求出总和为 sum 的所有组合，组合需要去重。这一题是第 39 题的加强版，第 39 题中元素可以重复利用(重复元素可无限次使用)，这一题中元素只能有限次数的利用，因为存在重复元素，并且每个元素只能用一次(重复元素只能使用有限次)

+# [2021. Brightest Position on Street](https://leetcode.com/problems/brightest-position-on-street/)
+
+
+## 题目
+
+A perfectly straight street is represented by a number line. The street has street lamp(s) on it and is represented by a 2D integer array `lights`. Each `lights[i] = [positioni, rangei]` indicates that there is a street lamp at position `positioni` that lights up the area from `[positioni - rangei, positioni + rangei]` (**inclusive**).
+
+The **brightness** of a position `p` is defined as the number of street lamp that light up the position `p`.
+
+Given `lights`, return *the **brightest** position on the street. If there are multiple brightest positions, return the **smallest** one.*
+
+**Example 1:**
+
+![https://assets.leetcode.com/uploads/2021/09/28/image-20210928155140-1.png](https://assets.leetcode.com/uploads/2021/09/28/image-20210928155140-1.png)
+
+```
+Input: lights = [[-3,2],[1,2],[3,3]]
+Output: -1
+Explanation:
+The first street lamp lights up the area from [(-3) - 2, (-3) + 2] = [-5, -1].
+The second street lamp lights up the area from [1 - 2, 1 + 2] = [-1, 3].
+The third street lamp lights up the area from [3 - 3, 3 + 3] = [0, 6].
+
+Position -1 has a brightness of 2, illuminated by the first and second street light.
+Positions 0, 1, 2, and 3 have a brightness of 2, illuminated by the second and third street light.
+Out of all these positions, -1 is the smallest, so return it.
+
+```
+
+**Example 2:**
+
+```
+Input: lights = [[1,0],[0,1]]
+Output: 1
+Explanation:
+The first street lamp lights up the area from [1 - 0, 1 + 0] = [1, 1].
+The second street lamp lights up the area from [0 - 1, 0 + 1] = [-1, 1].
+
+Position 1 has a brightness of 2, illuminated by the first and second street light.
+Return 1 because it is the brightest position on the street.
+
+```
+
+**Example 3:**
+
+```
+Input: lights = [[1,2]]
+Output: -1
+Explanation:
+The first street lamp lights up the area from [1 - 2, 1 + 2] = [-1, 3].
+
+Positions -1, 0, 1, 2, and 3 have a brightness of 1, illuminated by the first street light.
+Out of all these positions, -1 is the smallest, so return it.
+
+```
+
+**Constraints:**
+
+- `1 <= lights.length <= 105`
+- `lights[i].length == 2`
+- `108 <= positioni <= 108`
+- `0 <= rangei <= 108`
+
+## 题目大意
+
+一条完全笔直的街道由一条数字线表示。街道上有路灯，由二维数据表示。每个 `lights[i] = [positioni, rangei]` 表示位置 `i` 处有一盏路灯，灯可以照亮从 `[positioni - rangei, positioni + rangei]` （含）的区域。 位置 `p` 的亮度定义为点亮位置 `p` 的路灯数量。 给定路灯，返回街道上最亮的位置。如果有多个最亮的位置，则返回最小的一个。
+
+## 解题思路
+
+- 先将每个路灯的起始和终点位置计算出来。这样我们得到了一堆坐标点。假设灯照亮的范围是 [A, B]，那么在坐标轴上 A 坐标点处 + 1， B + 1 坐标点处 -1 。这样处理的含义是：坐标点 A 可以被一盏灯照亮，所以它照亮次数加一，坐标点 B + 1 出了灯照亮的范围了，所以照亮次数减一。那么从坐标轴坐标开始扫一遍，每次遇到 + 1 的时候就 + 1，遇到 - 1 的地方就 - 1。如此可以算出某个坐标点处，可以被灯照亮的总次数。
+- 需要注意的点是，题目给的测试数据可能会有单点照亮的情况，即某一盏灯只照亮一个坐标点，灯照范围为 0。同一个坐标点也可能是多个灯的起点。用一个 map 去重坐标点即可。
+
+## 代码
+
+```go
+package leetcode
+
+import (
+	"sort"
+)
+
+type lightItem struct {
+	index int
+	sign  int
+}
+

+	lightMap, lightItems := map[int]int{}, []lightItem{}
+	for _, light := range lights {
+		lightMap[light[0]-light[1]] += 1
+		lightMap[light[0]+light[1]+1] -= 1
+	}
+	for k, v := range lightMap {
+		lightItems = append(lightItems, lightItem{index: k, sign: v})
+	}
+	sort.SliceStable(lightItems, func(i, j int) bool {
+		return lightItems[i].index < lightItems[j].index
+	})
+	res, border, tmp := 0, 0, 0
+	for _, v := range lightItems {
+		tmp += v.sign
+		if border < tmp {
+			res = v.index
+			border = tmp
+		}
