class Solution { public int removeElement(int[] nums, int val) { int i=0,j=nums.length-1;//i-左指针;j-右指针 while (i<=j){ if(nums[i]==val){ nums[i]=nums[j];//得到索引j的值,无需把索引j的值改为索引i的值 j--; }else i++; } return j+1
If a[i]!=a[i+1], then run a loop from i=0 to i=n-2, and then push a[i] into the res array. a[n-1] element is added to the res array. Finally, return the res array. Code Implementation C++ Java Python #include<bits/stdc++.h> using namespace std; void removeDuplicates...
Given a sorted array, remove the duplicates in place such that each element appear onlyonceand 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 arraynums=[1,1,2], Your function should return len...
Note that the input array is passed in by reference, which means modification to the input array will be known to the caller as well. Internally you can think of this: // nums is passed in by reference. (i.e., without making a copy) int len = removeElement(nums, val); // any m...
