一.题目 Description 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 by modifying the input array in-place with O(1) e
第一次做到数组双指针的题目是80: 因为python的List是可以用以下代码来删除元素的: del List[index] 所以当时的我直接用了暴力删除第三个重复元素的做法,大概代码如下: n = len(nums) for i in range(n): if 重复了第i个: del nums[i] i -= 1 在出来7%+5%的提交成功以后,我去看了题解,才发现了可以用双指针做... 在宫水三叶姐的题解中,能使用双指针的本质是利用了「数组有序 & 保留逻辑」两大主要性质.最早接触双指针,还
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 by modifying the input array in-place with O(1) extra memory. Ex
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. 难点就一个,就是要考虑到连续3个和3个以上的情况. /** * Definition for singly-linke
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.
