1 题目 Given a sorted integer array without duplicates, return the summary of its ranges. For example, given [0,1,2,4,5,7], return ["0->2","4->5","7"]. 接口:public List<String> summaryRanges(int[] nums); 2 思路 给定一个排序好的…

Summary Ranges Given a sorted integer array without duplicates, return the summary of its ranges. Example 1: Input: [0,1,2,4,5,7] Output: ["0->2","4->5","7"] Explanation: 0,1,2 form a continuous range; 4,5 form a contin…

vector<string> summaryRanges(vector<int>& nums) { int nums_len = nums.size(); vector<string> res; ) return res; ; i < nums_len;) { int start = i, end = i; < nums_len && nums[end + ] == nums[end] + ) end++; if (end >…

Given a sorted integer array without duplicates, return the summary of its ranges. For example, given [0,1,2,4,5,7], return ["0->2","4->5","7"]. 就是概括区间的方式把一个数组表示下来,例如123用1->3代替,自己写的很乱 ,维护两个指针就可以了: class Solution { pu…

Given a sorted integer array without duplicates, return the summary of its ranges. For example, given [0,1,2,4,5,7], return ["0->2","4->5","7"]. My Solution: vector<string> summaryRanges(vector<int>& num…

题目: 228. Summary Ranges Given a sorted integer array without duplicates, return the summary of its ranges. For example, given [0,1,2,4,5,7], return ["0->2","4->5","7"]. 答案: 就是找连续的序列. 直接判断相邻数据大小是否相差为1即可,主要是注意最后的数字要特殊考虑一下…

话说博主在写Max Chunks To Make Sorted II这篇帖子的解法四时,写到使用单调栈Monotone Stack的解法时,突然脑中触电一般,想起了之前曾经在此贴LeetCode All in One 题目讲解汇总(持续更新中...)的留言区中说要写单调栈的总结帖,当时答应了要写,就去LeetCode上看标记为Stack的题,可是发现有好多题,而且很多用的不是单调栈,于是博主一个一个的看了起来,但是无奈太多了,一直没有时间全部看完,就一直没有动笔写.虽说时间就像那啥,挤挤总会有的…

会在近期陆续地完成数组篇的整理,希望对找工作的小伙伴有所帮助.   1.Two Sum:两数相加为一固定值,求其下标.一次遍历数组,用一个hash表存储已经访问过的数及其下标,对于新访问的数value,查hash表中是否有target-value的值,如果有,程序输出,如果没有,继续访问下一个数直到访问完.   public int[] twoSum(int[] nums, int target) { Map<Integer, Integer> hash = new HashMap<&g…

Missing Ranges Given a sorted integer array where the range of elements are [lower, upper] inclusive, return its missing ranges. For example, given [0, 1, 3, 50, 75], lower = 0 and upper = 99, return ["2", "4->49", "51->74&q…
