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...

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
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 ...
