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...
Remove Duplicates from Sorted Array Remove Duplicates from Sorted Array 删除有序数组中重复的元素;返回新的长度;不允许新建额外的数组 解决思路 设立2个游标:游标index用来遍历数组,游标newLen用来插入元素 遍历数组,两两比较;如果不同,将index指向的元素复制到newLen指向位置;newLen与index各自右移 输出:......
What if duplicates are allowed at mosttwice? For example, 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]. Hide Tags ArrayTwo Pointers 这个很容易判断了,设两个index,一个是遍历的,一个是指向返回的最后位置,因为已经排序了,所以判...
83. Remove Duplicates from Sorted List Given a sorted linked list, delete all duplicates such that each element appear onlyonce. For example, Given1->1->2, return1->2. Given1->1->2->3->3, return1->2->3. 对于给定排序链表进行去重处理。
【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) { ...
与Remove Duplicates from Sorted Array思路一样,也是用快慢指针。两者共同本质就是: 什么情况下慢指针(left)移动(同时移动元素) 1. I: if(nums[i-1]!=nums[i]) nums[left++]=nums[i] 1. II: if(nums[i-1]!=nums[i]||count<=2) nums[left++]=nums[i] ...
Remove Duplicates from Sorted List II java编程算法 该文讲述了如何删除排序链表中的重复节点,并保留非重复节点。通过先构建一个虚拟头节点来处理头结点,然后遍历链表,如果当前节点和下一个节点的值相同,则删除当前节点,否则将当前节点和下一个节点连接起来。遍历结束后,返回虚拟头节点的下一个节点即可。该解法使用...
I am trying to remove duplicates from a comma separated list and sort it alphabetically. I'm not sure of the best method. I have achieved what I want the long way, but I think I should be able to use a Sorted Set, list or collection to achieve the same thing far more efficiently....
To remove duplicates from a Python list while preserving order, create a dictionary from the list and then extract its keys as a new list: list(dict.fromkeys(my_list)).
