26. Remove Duplicates from Sorted Array 题目链接 思路一:单指针法,遍历数组,遇到和下一个元素不同的把这个元素按顺序保存到数组的前面,用指针记录保存的个数,注意数组只有一个元素和遍历到最后俩元素的特殊情况。 class Solution: def removeDuplicates(self,nums): sum = 0 if len(nums) <= 1: return 1 ...
By applying the UNIQUE function, we can retrieve unique values and remove any duplicates in Excel. The UNIQUE function keeps only the first instance and ignores the rest of a dataset. It returns an array.Insert the following UNIQUE formula in cell B6: ...
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...
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...
