Given a sorted array, remove the duplicates in place such that each element appear onlyonceand 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 arraynums=[1,1,2], Your function should return len...

2) Remove duplicates using filter and indexOf TheindexOf()method returns the first index at which a given element can be found in the array, or -1 if it is not present. Thefilter()method creates a shallow copy of a portion of a given array, filtered down to just the elements from t...
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...

Leetcode每日一题:26.remove-duplicates-from-sorted-array(删除排序数组中的重复项),正常思维:依次遍历到尾,期间把经过的元素(不重复的and重复出现只取一个)依次push_back到vector里然后把前面的全删除即可;简洁版:因为题目说了不考虑超出新长度后的元素,所以一个f
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 ...
