Given a sorted array, remove the duplicates in place such that each element appear only once and return the new length. Do not allocate extra space for another array, you must do this in place with constant memory. For example, Given input array nums = [1,1,2], Your function should re...
二、Remove Duplicates from Sorted Array2.1 问题题目大意理解,就是对数组进行元素去重,然后返回去处重复之后的长度,无论我们对数组做了什么的修改,都没有关系的,只要保证再返回的长度之内的数组正确性即可。因为最后是根据长度来遍历的,因此我们不用担心。
题目 Given a sorted array nums, remove the duplicates in-place such that duplicates appeared at most twice and return the new length. Do not allocate extra space for another array, you must do this by modifying the input array in-place with O(1) extra memory. Example 1: Given nums=[1,...
Given an integer array nums sorted in non-decreasing order, remove the duplicates in-place such that each unique element appears only once. The relative order of the elements should be kept the same. Then return the number of unique elements in nums. Consider the number of unique elements of...
Can you solve this real interview question? Remove Duplicates from Sorted Array - Given an integer array nums sorted in non-decreasing order, remove the duplicates in-place [https://en.wikipedia.org/wiki/In-place_algorithm] such that each unique element
26. Remove Duplicates from Sorted Array(重要!) 一 once Do not allocate extra space for another array, you must do this in place with constant memory. For example, Given input array nums = [1,1,2],2, with the first two elements of nums being 1...

给你一个非严格递增排列的数组nums,请你原地删除重复出现的元素,使每个元素只出现一次,返回删除后数组的新长度。元素的相对顺序应该保持一致。然后返回nums中唯一元素的个数。 考虑nums的唯一元素的数量为k,你需要做以下事情确保你的题解可以被通过: 更改数组nums,使nums的前k个元素包含唯一元素,并按照它们最初在num...
该题设部分有两个主要的关键点,其一是数组自身有顺序;其二是数组的本身返回仍是以袁数组nums的内容返回,预期不是采用新数组方式。 具体的一些复杂要求,可以去查看相关题设说明。 方法一: 使用双指针的方法,两个指针比较来进行移动. 其中i代表慢的指针,需要更新nums数组的值 ...
