715. Range 模块 Range 模块是跟踪数字范围的模块.你的任务是以一种有效的方式设计和实现以下接口. addRange(int left, int right) 添加半开区间 [left, right),跟踪该区间中的每个实数.添加与当前跟踪的数字部分重叠的区间时,应当添加在区间 [left, right) 中尚未跟踪的任何数字到该区间中. queryRange(int left, int right) 只有在当前正在跟踪区间 [left, right) 中的每一个实数时,才返回 t…

［抄题］: 给出若干闭合区间,合并所有重叠的部分. 给出的区间列表 => 合并后的区间列表: [ [ [1, 3], [1, 6], [2, 6], => [8, 10], [8, 10], [15, 18] [15, 18] ] ] [暴力解法]: 时间分析: 空间分析: ［思维问题］: ［一句话思路］: 区间类问题,先把起点排序才能具有逐个合并的能力和性质 ［输入量］:空: 正常情况:特大:特小:程序里处理到的特殊情况:异常情况(不合法不合理的输入): ［画图］: ［一刷］: lambda…

突然很想刷刷题,LeetCode是一个不错的选择,忽略了输入输出,更好的突出了算法,省去了不少时间. dalao们发现了任何错误,或是代码无法通过,或是有更好的解法,或是有任何疑问和建议的话,可以在对应的随笔下面评论区留言,我会及时处理,在此谢过了. 过程或许会很漫长,也很痛苦,慢慢来吧. 编号 题名 过题率 难度 1 Two Sum 0.376 Easy 2 Add Two Numbers 0.285 Medium 3 Longest Substring Without Repeating C…

645. Set Mismatch The set S originally contains numbers from 1 to n. But unfortunately, due to the data error, one of the numbers in the set got duplicated to another number in the set, which results in repetition of one number and loss of another nu…
