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 A = [1,1,2], Your function should retur...

26 Remove Duplicate from sorted array publicclassSolution {publicintremoveDuplicates(int[] nums) {if(nums ==null|| nums.length == 0) {return0; }intsize = 1;for(inti = 1; i < nums.length; i++) {if(nums[i] != nums[i - 1]) { nums[size]=nums[i]; size++; } }returnsize; }...
【思路】 在Remove Duplicates from Sorted Array一题中,我们只需要记录目标数组下一个该插入的位置,让后续符合要求的元素插入该位置即可。利用同样的思想,只是在比较的时候不是和前一个元素比较,而是前两个元素。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 public int removeDuplicates(int[] nums) { ...

Given sorted array A =[1,1,1,2,2,3], Your function should return length =5, and A is now[1,1,2,2,3]. 典型的两指针问题 两个指针指向初始位置,一个指针i开始遍历,记录出现相同数的个数 如果遍历的指针i等于其前面的指针index且cnt个数超过两个,则继续移动遍历的指针 ...

Time Complexity Analysis For Remove Duplicate Elements From Array The array is sorted in the first step, which takes O(NlogN) time. Next, the loop from 0 to n-2 is run, which takes O(N) time. Therefore, this method’s worst-case time complexity for eliminating duplicates from the array...
Time Complexity: O(n), traversing through elements of the array.Space Complexity: O(n), using HashSet to store elements. Remove Duplicates from Array Using Sorting In this approach, we first sort the array. When sorted, duplicate elements will be next to each other. We then iterate through...
