Given an array containing n distinct numbers taken from 0, 1, 2, ..., n, find the one that is missing from the array. For example, Given nums = [0, 1, 3] return 2. Note: Your algorithm should run in linear runtime complexity. Could you implement it u…

Given a sorted integer array where the range of elements are [0, 99] inclusive, return its missing ranges.For example, given [0, 1, 3, 50, 75], return [“2”, “4->49”, “51->74”, “76->99”] 这道题让我们求缺失区间,跟之前那道Summary Ranges很类似,这道题让我们求缺失的空间,给了一个空间的范围[lo…

Given an unsorted integer array, find the first missing positive integer. For example,Given [1,2,0] return 3,and [3,4,-1,1] return 2. Your algorithm should run in O(n) time and uses constant space. 这道题让我们找缺失的首个正数,由于限定了O(n)的时间,所以一般的排序方法都不能用,最开始我没有看到还限…
