Given a sorted linked list, delete all duplicates such that each element appear only once. For example,Given 1->1->2, return 1->2.Given 1->1->2->3->3, return 1->2->3. 如题目所诉,去除递增链表中重复值的节点. 刚开始思路如下: 设置一个指针用于遍历全部节点 让每个节点和其next节点值比较…
Remove Duplicates from Sorted List : Given a sorted linked list, delete all duplicates such that each element appear only once. For example,Given 1->1->2, return 1->2.Given 1->1->2->3->3, return 1->2->3. public ListNode deleteDu…
[试题描述]定义一个函数,输入一个链表,删除无序链表中重复的节点 [参考代码] 方法一: Without a buffer, we can iterate with two pointers: "current" does a normal iteration, while "runner" iterates through all prior nodes to check for dups Runner will only see one dup per node…
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 = […
Given a sorted array nums, 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 by modifying the input array in-place with O(1) extra memory.…
Given a sorted linked list, delete all duplicates such that each element appear only once. Example 1: Input: 1->1->2 Output: 1->2 Example 2: Input: 1->1->2->3->3 Output: 1->2->3 题意: 有序链表去重 思路: 代码: class Solution { public ListNod…
Given a sorted linked list, delete all duplicates such that each element appear only once. For example,Given 1->1->2, return 1->2.Given 1->1->2->3->3, return 1->2->3. 设置2个指针,cur 和next. 当cur的值与next的值相等时,cur.next= next.next 更新ne…
Given a sorted linked list, delete all duplicates such that each element appear only once. For example,Given 1->1->2, return 1->2.Given 1->1->2->3->3, return 1->2->3. 思路:两个指针,一个指向当前节点cur,一个指向下一个节点nx,终止条件,也就是比较了len-1次. 比较若不等,则两指针…
Given a sorted linked list, delete all nodes that have duplicate numbers, leaving only distinct numbers from the original list. For example,Given 1->2->3->3->4->4->5, return 1->2->5.Given 1->1->1->2->3, return 2->3.…
I.Given a sorted linked list, delete all duplicates such that each element appear only once. For example,Given1->1->2, return1->2.Given1->1->2->3->3, return1->2->3. PS:遍历,而后记录pre,并删除后续重复node /** * Definition for singly-linked li…
Given a sorted array nums, remove the duplicates in-place such that duplicates appeared at most twice and return the new length. Do not allocate extra space for another array, you must do this by modifying the input array in-place with O(1) extra mem…
[LeetCode] Remove Duplicates from Sorted Array 有序数组中去除重复项 描述 Given a sorted array nums, 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…

Follow up for "Remove Duplicates":What if duplicates are allowed at most twice? For example,Given sorted array nums = [1,1,1,2,2,3], Your function should return length = 5, with the first five elements of nums being 1, 1, 2, 2 and 3. It doesn't…
